Re: [Amel Yacht Owners] alternator-to-battery charger

Alan Leslie
 

Hello
It's not the Amel system it has to be compatible with, it is the alternator and the batteries.
It is likely that your alternator has a standard automotive regulator in it and you are correct, this is no good for charging deep cycle batteries.
Look in the files section and you will find information on installation of a Sterling regulator and also of a Next Step regulator (what I have). Both systems work with deep cycle batteries including AGM.
Good luck

Good morning,

The toggle switch (bottom switch) of my Jabsco 37045 electric toilet is working intermittently.

jabsco part 37047-1000 is for the whole switch (and doesn't seem to be available).

I just need to replace the toggle switch (bottom black switch).

Any part number or advice?

Thanks in advance.

Hello Kent,

I just changed my zinc (3 weeks ago), I scuba dove yesterday, they (thankfully) look good.
But crazy how the propeller (cleaned 2 weeks ago) was already starting to get dirty here…

Anyway, I will do as your describe. Very logical way to find a leak (if there is one). All clear.

I heard of not over zinc either, but keep the idea of the fish looking zinc. One of my neighbors on a steel sailboat has one.

Thanks so much for the detail explanation…
Alexandre

Yes, it can matter, Alex.  If you are at
the dock and know that your zincs are intact, and you find a
higher potential (less negative voltage) for example -750mv,
I would first disconnect shore power and test again.  If it
is then -900 to -1050mv you are getting a voltage from the
dock or another nearby boat.  If it still reads -750mv, you
may have a DC current leak on your boat.  Turn everything
off, including all breakers and your main battery switches.
 If it then tests good, turn the breakers on one at a time
to see which one is causing the problem.  If, with all 24v
breakers off, it still reads -750mv, you could have a wiring
issue on the negative side.  That's a real PITA to
chase down.  I found a couple of miswirings, but could
never correct it completely (i.e. I still had continuity
between the bonding system and battery negative.  The
galvanic/electrolytic corrosion expert I hired said that he
didn't believe I had a current leak, and if I did it
might be impossible to find.  He thought I was just
under-zinc'd.  I found some 7 inch rudder zincs made by
Camp (better quality than Martyr and some other brands).  I
put them on the rudder and have been right at -950mv since
and the zincs seem to be lasting for a lot longer.  They
are barely eroded after 4 months.  I still hang a
"guppy" zinc (looks like a fish) over the side if
I'm going to be somewhere for more than a few days.
 This brings my hull potential up to -990mv and affords a
little more protection.I check hull potential
every time I drop anchor or tie up to a dock, or at least
once a month.
Is that clear?  If not
I'll try something else.Kent "Rusty"

Good afternoon Kent,



Glad you are joining this discussion, I just ordered it
(like I didn’t had enough part or tools onboard…)

I will definitely make sure to rinse it, etc.



So with this silver electrode I will be able to check in the
water.

Does it matter they are vessel around?



Thanks again!

Hope the eye is doing better…

it.  A booklet explaining its use comes with it.Kent

Degraded continuity    Alexandre, The number



900 refers to potential, which is also measured using a



multi meter , but you also have to have a silver
cathode

,



expensive. It would probably be best for you to have a



marine electrician perform that measurement  if you
are

not



familiar with multi meters . It would not take them
but

a



few minutes. Just measuring that you have continuity

, you



would just listen for the beep , the number will also

change



from 0 to 1 or 1 to 0 ,I cannot remember , just listen

for



the beep.Pat SM123

The way you describe it sounds

Do



you have to check several items? quadrant then ground

copper

Alexandre, Its pretty simple,



take a wire



and clip it onto the quadrant



where the ground wires



connect , or to the



copper ground strap in the bilge , then



connect the wire to one side of a multi meter ,



say the



black lead and then place the red



lead on the zincs on your



rudder . You of



course have to set your meter to the



continuity setting , its simple , have someone



that knows



how to use a meter show you or



follow instructions provided



with your



meter.If you have continuity your meter will beep



and the numbers change. While its vital that



you have



continuity , as I have just



learned , that does not mean



that you have



adequate continuity. While you are in the



water you can have the potential checked which



gives you a



better picture of the state of



protection. Don't ask me



to explain



potential , I only have a foggy idea of what it



means and could not put it into words.







Hope this helps,







Pat SM123

Good morning



Pat,























Thanks for

Please forgive my ignorance,



but how do you measure the



continuity…











I hate to



admit it, I didn’t know about it when I did the



last haul out in March 2015, I then read on the

the owner manual.











And will



definitely want to do it next year.











But how do you do it?

I assume you can only do it on land.

Before my boat went into back



into the











water yesterday , I checked for continuity



between the











copper strap and the zincs and I did have



continuity.



Later











, I had two marine



electricians on the boat and they



checked











the potential



from the quadrant and found it to be only



560











, they tell me that they would expect to see



about 900.



900











would insure that the zincs



are protecting the metal



parts











of the boat.



We can only speculate that the connection











between the



quadrant wire and the zincs have been degraded



.











There may not be enough contact between the



zinc bolt



and











the strap inside  the rudder



, it would only be the











threaded area of the bolt and the strap , and



stainless



is











not the best metal as a



conductor . Bottom line is that



I











need more



zinc protection/contact. They suggested that



we











install a large zinc on the hull with two



bronze bolts (











better conductivity )through the hull , wired



directly



to











the strap in the bilge. I am



writing this to inform the











group , that just because you



have continuity , does



not











mean that you



have adequate contact/protection.

Re: [Amel Yacht Owners] Degraded continuity

Yes, it can matter, Alex. If you are at the dock and know that your zincs are intact, and you find a higher potential (less negative voltage) for example -750mv, I would first disconnect shore power and test again. If it is then -900 to -1050mv you are getting a voltage from the dock or another nearby boat. If it still reads -750mv, you may have a DC current leak on your boat. Turn everything off, including all breakers and your main battery switches. If it then tests good, turn the breakers on one at a time to see which one is causing the problem. If, with all 24v breakers off, it still reads -750mv, you could have a wiring issue on the negative side. That's a real PITA to chase down. I found a couple of miswirings, but could never correct it completely (i.e. I still had continuity between the bonding system and battery negative. The galvanic/electrolytic corrosion expert I hired said that he didn't believe I had a current leak, and if I did it might be impossible to find. He thought I was just under-zinc'd. I found some 7 inch rudder zincs made by Camp (better quality than Martyr and some other brands). I put them on the rudder and have been right at -950mv since and the zincs seem to be lasting for a lot longer. They are barely eroded after 4 months. I still hang a "guppy" zinc (looks like a fish) over the side if I'm going to be somewhere for more than a few days. This brings my hull potential up to -990mv and affords a little more protection.
I check hull potential every time I drop anchor or tie up to a dock, or at least once a month.

Is that clear? If not I'll try something else.

Good afternoon Kent,

Glad you are joining this discussion, I just ordered it (like I didn’t had enough part or tools onboard…)
I will definitely make sure to rinse it, etc.

So with this silver electrode I will be able to check in the water.
Does it matter they are vessel around?

Thanks again!
Hope the eye is doing better…

That's the one I have, Alex. Be sure
to rinse well in fresh water and allow to dry before storing

Degraded continuity Alexandre, The number

900 refers to potential, which is also measured using a

multi meter , but you also have to have a silver cathode
,

expensive. It would probably be best for you to have a

marine electrician perform that measurement if you are
not

familiar with multi meters . It would not take them but
a

few minutes. Just measuring that you have continuity
, you

would just listen for the beep , the number will also
change

from 0 to 1 or 1 to 0 ,I cannot remember , just listen
for

the beep.Pat SM123

The way you describe it sounds

very simple… at the next haul it will do that and you

mentioned the number should be 900 (?)

Do

you have to check several items? quadrant then ground
copper

strap in the bilge or 1 is enough?



Thanks again.

Alexandre, Its pretty simple,

take a wire

and clip it onto the quadrant

where the ground wires

connect , or to the

copper ground strap in the bilge , then

connect the wire to one side of a multi meter ,

say the

black lead and then place the red

lead on the zincs on your

rudder . You of

course have to set your meter to the

continuity setting , its simple , have someone

that knows

how to use a meter show you or

follow instructions provided

with your

meter.If you have continuity your meter will beep

and the numbers change. While its vital that

you have

continuity , as I have just

learned , that does not mean

that you have

adequate continuity. While you are in the

water you can have the potential checked which

gives you a

better picture of the state of

protection. Don't ask me

to explain

potential , I only have a foggy idea of what it

means and could not put it into words.



Hope this helps,



Pat SM123

Good morning

Pat,











Thanks for

sharing the information.











Please forgive my ignorance,

but how do you measure the

continuity…





I hate to

admit it, I didn’t know about it when I did the

last haul out in March 2015, I then read on the

forum and

the owner manual.





And will

definitely want to do it next year.





But how do you do it?

(pictures rather than words would be

so

nice)…











I assume you can only do it on land.

Before my boat went into back

into the





water yesterday , I checked for continuity

between the





copper strap and the zincs and I did have

continuity.

Later





, I had two marine

electricians on the boat and they

checked





the potential

from the quadrant and found it to be only

560





, they tell me that they would expect to see

about 900.

900





would insure that the zincs

are protecting the metal

parts





of the boat.

We can only speculate that the connection





between the

quadrant wire and the zincs have been degraded

.





There may not be enough contact between the

zinc bolt

and





the strap inside the rudder

, it would only be the





threaded area of the bolt and the strap , and

stainless

is





not the best metal as a

conductor . Bottom line is that

I





need more

zinc protection/contact. They suggested that

we





install a large zinc on the hull with two

bronze bolts (





better conductivity )through the hull , wired

directly

to





the strap in the bilge. I am

writing this to inform the





group , that just because you

have continuity , does

not





mean that you

have adequate contact/protection.

Re: [Amel Yacht Owners] Degraded continuity

Patrick McAneny
 

Kent, Yes, my electrician said he would like to see at least 900 or higher . What do you get when you have checked ? I think I will buy the one Eric sent link to, could save problems down the road. I told my electrician about your nightmare.

Alex,
You check continuity when on the hard.  The reference electrode is used when the boat is in the water.  I believe that Amel SMs should be at (-)900-1050 millivolts.

Good morning Pat,

The way you describe it sounds very simple… at the next haul it will do that and you mentioned the number should be 900 (?)
Do you have to check several items? quadrant then ground copper strap in the bilge or 1 is enough?

Thanks again.
Sincerely, Alexandre

Alexandre, Its pretty simple, take a wire
and clip it onto the quadrant where the ground wires
connect , or to the copper ground strap in the bilge , then
connect the wire to one side of a multi meter , say the
black lead and then place the red lead on the zincs on your
rudder . You of course have to set your meter to the
continuity setting , its simple , have someone that knows
how to use a meter show you or follow instructions provided
with your meter.If you have continuity your meter will beep
and the numbers change. While its vital that you have
continuity , as I have just learned , that does not mean
that you have adequate continuity. While you are in the
water you can have the potential checked which gives you a
better picture of the state of protection. Don't ask me
to explain potential , I only have a foggy idea of what it
means and could not put it into words.

Hope this helps,

Pat SM123

Good morning Pat,





Thanks for sharing the information.





Please forgive my ignorance, but how do you measure the
continuity…


I hate to admit it, I didn’t know about it when I did the
last haul out in March 2015, I then read on the forum and
the owner manual.


And will definitely want to do it next year.


But how do you do it? (pictures rather than words would be
so nice)…





I assume you can only do it on land.

Before my boat went into back into the


water yesterday , I checked for continuity between the


copper strap and the zincs and I did have continuity.
Later


, I had two marine electricians on the boat and they
checked


the potential from the quadrant and found it to be only
560


, they tell me that they would expect to see about 900.
900


would insure that the zincs are protecting the metal
parts


of the boat. We can only speculate that the connection


between the quadrant wire and the zincs have been degraded
.


There may not be enough contact between the zinc bolt
and


the strap inside  the rudder , it would only be the


threaded area of the bolt and the strap , and stainless
is


not the best metal as a conductor . Bottom line is that
I


need more zinc protection/contact. They suggested that
we


install a large zinc on the hull with two bronze bolts (


better conductivity )through the hull , wired directly
to


the strap in the bilge. I am writing this to inform the


group , that just because you have continuity , does
not


mean that you have adequate contact/protection.

Re: [Amel Yacht Owners] Degraded continuity

Alexandre Uster von Baar
 

Good afternoon Kent,

Glad you are joining this discussion, I just ordered it (like I didn’t had enough part or tools onboard…)
I will definitely make sure to rinse it, etc.

So with this silver electrode I will be able to check in the water.
Does it matter they are vessel around?

Thanks again!
Hope the eye is doing better…

Alexandre

That's the one I have, Alex.  Be sure
to rinse well in fresh water and allow to dry before storing
it.  A booklet explaining its use comes with it.Kent

Degraded continuity    Alexandre, The number

900 refers to potential, which is also measured using a

multi meter , but you also have to have a silver cathode
,

expensive. It would probably be best for you to have a

marine electrician perform that measurement  if you are
not

familiar with multi meters . It would not take them but
a

few minutes. Just measuring that you have continuity
, you

would just listen for the beep , the number will also
change

from 0 to 1 or 1 to 0 ,I cannot remember , just listen
for

the beep.Pat SM123

The way you describe it sounds

very simple… at the next haul it will do that and you

mentioned the number should be 900 (?)

Do

you have to check several items? quadrant then ground
copper

strap in the bilge or 1 is enough?



Thanks again.

Alexandre, Its pretty simple,

take a wire

and clip it onto the quadrant

where the ground wires

connect , or to the

copper ground strap in the bilge , then

connect the wire to one side of a multi meter ,

say the

black lead and then place the red

lead on the zincs on your

rudder . You of

course have to set your meter to the

continuity setting , its simple , have someone

that knows

how to use a meter show you or

follow instructions provided

with your

meter.If you have continuity your meter will beep

and the numbers change. While its vital that

you have

continuity , as I have just

learned , that does not mean

that you have

adequate continuity. While you are in the

water you can have the potential checked which

gives you a

better picture of the state of

protection. Don't ask me

to explain

potential , I only have a foggy idea of what it

means and could not put it into words.



Hope this helps,



Pat SM123

Good morning

Pat,











Thanks for

sharing the information.











Please forgive my ignorance,

but how do you measure the

continuity…





I hate to

admit it, I didn’t know about it when I did the

last haul out in March 2015, I then read on the

forum and

the owner manual.





And will

definitely want to do it next year.





But how do you do it?

(pictures rather than words would be

so

nice)…











I assume you can only do it on land.

Before my boat went into back

into the





water yesterday , I checked for continuity

between the





copper strap and the zincs and I did have

continuity.

Later





, I had two marine

electricians on the boat and they

checked





the potential

from the quadrant and found it to be only

560





, they tell me that they would expect to see

about 900.

900





would insure that the zincs

are protecting the metal

parts





of the boat.

We can only speculate that the connection





between the

quadrant wire and the zincs have been degraded

.





There may not be enough contact between the

zinc bolt

and





the strap inside  the rudder

, it would only be the





threaded area of the bolt and the strap , and

stainless

is





not the best metal as a

conductor . Bottom line is that

I





need more

zinc protection/contact. They suggested that

we





install a large zinc on the hull with two

bronze bolts (





better conductivity )through the hull , wired

directly

to





the strap in the bilge. I am

writing this to inform the





group , that just because you

have continuity , does

not





mean that you

have adequate contact/protection.

It's connected to the keel via a bolt at the bottom of the sump.

Hi Pat,

So what is the bilge ground strap connected to? I suppose the iron keel?  Should we be looking at the continuity between the keel and the zincs?

Alexandre, Sorry I missed the second part of your question. I would check it at the strap in the bilge , that way it also confirms that you have continuity between the strap and the quadrant connection . That's actually what its all about , confirming contact between the ground strap in the bilge and the zincs on your rudder.

Good morning Pat,

The way you describe it sounds very simple… at the next haul it will do that and you mentioned the number should be 900 (?)
Do you have to check several items? quadrant then ground copper strap in the bilge or 1 is enough?

Thanks again.
Sincerely, Alexandre

Alexandre, Its pretty simple, take a wire
and clip it onto the quadrant where the ground wires
connect , or to the copper ground strap in the bilge , then
connect the wire to one side of a multi meter , say the
black lead and then place the red lead on the zincs on your
rudder . You of course have to set your meter to the
continuity setting , its simple , have someone that knows
how to use a meter show you or follow instructions provided
with your meter.If you have continuity your meter will beep
and the numbers change. While its vital that you have
continuity , as I have just learned , that does not mean
that you have adequate continuity. While you are in the
water you can have the potential checked which gives you a
better picture of the state of protection. Don't ask me
to explain potential , I only have a foggy idea of what it
means and could not put it into words.

Hope this helps,

Pat SM123

Good morning Pat,





Thanks for sharing the information.





Please forgive my ignorance, but how do you measure the
continuity…


I hate to admit it, I didn’t know about it when I did the
last haul out in March 2015, I then read on the forum and
the owner manual.


And will definitely want to do it next year.


But how do you do it? (pictures rather than words would be
so nice)…





I assume you can only do it on land.

Before my boat went into back into the


water yesterday , I checked for continuity between the


copper strap and the zincs and I did have continuity.
Later


, I had two marine electricians on the boat and they
checked


the potential from the quadrant and found it to be only
560


, they tell me that they would expect to see about 900.
900


would insure that the zincs are protecting the metal
parts


of the boat. We can only speculate that the connection


between the quadrant wire and the zincs have been degraded
.


There may not be enough contact between the zinc bolt
and


the strap inside  the rudder , it would only be the


threaded area of the bolt and the strap , and stainless
is


not the best metal as a conductor . Bottom line is that
I


need more zinc protection/contact. They suggested that
we


install a large zinc on the hull with two bronze bolts (


better conductivity )through the hull , wired directly
to


the strap in the bilge. I am writing this to inform the


group , that just because you have continuity , does
not


mean that you have adequate contact/protection.

Mike, The strap is connected to the connection at the quadrant , which in turn is connected to the zincs, that's my understanding.

Hi Pat,
So what is the bilge ground strap connected to? I suppose the iron keel?  Should we be looking at the continuity between the keel and the zincs?

Alexandre, Sorry I missed the second part of your question. I would check it at the strap in the bilge , that way it also confirms that you have continuity between the strap and the quadrant connection . That's actually what its all about , confirming contact between the ground strap in the bilge and the zincs on your rudder.

Good morning Pat,

The way you describe it sounds very simple… at the next haul it will do that and you mentioned the number should be 900 (?)
Do you have to check several items? quadrant then ground copper strap in the bilge or 1 is enough?

Thanks again.
Sincerely, Alexandre

Alexandre, Its pretty simple, take a wire
and clip it onto the quadrant where the ground wires
connect , or to the copper ground strap in the bilge , then
connect the wire to one side of a multi meter , say the
black lead and then place the red lead on the zincs on your
rudder . You of course have to set your meter to the
continuity setting , its simple , have someone that knows
how to use a meter show you or follow instructions provided
with your meter.If you have continuity your meter will beep
and the numbers change. While its vital that you have
continuity , as I have just learned , that does not mean
that you have adequate continuity. While you are in the
water you can have the potential checked which gives you a
better picture of the state of protection. Don't ask me
to explain potential , I only have a foggy idea of what it
means and could not put it into words.

Hope this helps,

Pat SM123

Good morning Pat,





Thanks for sharing the information.





Please forgive my ignorance, but how do you measure the
continuity…


I hate to admit it, I didn’t know about it when I did the
last haul out in March 2015, I then read on the forum and
the owner manual.


And will definitely want to do it next year.


But how do you do it? (pictures rather than words would be
so nice)…





I assume you can only do it on land.

Date: Tuesday, August 30, 2016, 7:51 AM








 





























Before my boat went into back into the


water yesterday , I checked for continuity between the


copper strap and the zincs and I did have continuity.
Later


, I had two marine electricians on the boat and they
checked


the potential from the quadrant and found it to be only
560


, they tell me that they would expect to see about 900.
900


would insure that the zincs are protecting the metal
parts


of the boat. We can only speculate that the connection


between the quadrant wire and the zincs have been degraded
.


There may not be enough contact between the zinc bolt
and


the strap inside  the rudder , it would only be the


threaded area of the bolt and the strap , and stainless
is


not the best metal as a conductor . Bottom line is that
I


need more zinc protection/contact. They suggested that
we


install a large zinc on the hull with two bronze bolts (


better conductivity )through the hull , wired directly
to


the strap in the bilge. I am writing this to inform the


group , that just because you have continuity , does
not


mean that you have adequate contact/protection.

Re: [Amel Yacht Owners] Degraded continuity

Alex,
You check continuity when on the hard.  The reference electrode is used when the boat is in the water.  I believe that Amel SMs should be at (-)900-1050 millivolts.

Good morning Pat,

The way you describe it sounds very simple… at the next haul it will do that and you mentioned the number should be 900 (?)
Do you have to check several items? quadrant then ground copper strap in the bilge or 1 is enough?

Thanks again.
Sincerely, Alexandre

Alexandre, Its pretty simple, take a wire
and clip it onto the quadrant where the ground wires
connect , or to the copper ground strap in the bilge , then
connect the wire to one side of a multi meter , say the
black lead and then place the red lead on the zincs on your
rudder . You of course have to set your meter to the
continuity setting , its simple , have someone that knows
how to use a meter show you or follow instructions provided
with your meter.If you have continuity your meter will beep
and the numbers change. While its vital that you have
continuity , as I have just learned , that does not mean
that you have adequate continuity. While you are in the
water you can have the potential checked which gives you a
better picture of the state of protection. Don't ask me
to explain potential , I only have a foggy idea of what it
means and could not put it into words.

Hope this helps,

Pat SM123

Good morning Pat,





Thanks for sharing the information.





Please forgive my ignorance, but how do you measure the
continuity…


I hate to admit it, I didn’t know about it when I did the
last haul out in March 2015, I then read on the forum and
the owner manual.


And will definitely want to do it next year.


But how do you do it? (pictures rather than words would be
so nice)…





I assume you can only do it on land.

Subject: [Amel Yacht Owners] Degraded continuity


To: amelyachtowners@...


Date: Tuesday, August 30, 2016, 7:51 AM








 





























Before my boat went into back into the


water yesterday , I checked for continuity between the


copper strap and the zincs and I did have continuity.
Later


, I had two marine electricians on the boat and they
checked


the potential from the quadrant and found it to be only
560


, they tell me that they would expect to see about 900.
900


would insure that the zincs are protecting the metal
parts


of the boat. We can only speculate that the connection


between the quadrant wire and the zincs have been degraded
.


There may not be enough contact between the zinc bolt
and


the strap inside  the rudder , it would only be the


threaded area of the bolt and the strap , and stainless
is


not the best metal as a conductor . Bottom line is that
I


need more zinc protection/contact. They suggested that
we


install a large zinc on the hull with two bronze bolts (


better conductivity )through the hull , wired directly
to


the strap in the bilge. I am writing this to inform the


group , that just because you have continuity , does
not


mean that you have adequate contact/protection.

That's the one I have, Alex.  Be sure to rinse well in fresh water and allow to dry before storing it.  A booklet explaining its use comes with it.

Degraded continuity    Alexandre, The number
900 refers to potential, which is also measured using a
multi meter , but you also have to have a silver cathode ,
expensive. It would probably be best for you to have a
marine electrician perform that measurement  if you are not
familiar with multi meters . It would not take them but a
few minutes. Just measuring that you have continuity , you
would just listen for the beep , the number will also change
from 0 to 1 or 1 to 0 ,I cannot remember , just listen for
the beep.Pat SM123

continuity  Good morning Pat,

The way you describe it sounds
very simple… at the next haul it will do that and you
mentioned the number should be 900 (?)
Do
you have to check several items? quadrant then ground copper
strap in the bilge or 1 is enough?

Thanks again.
Sincerely,
Alexandre

Alexandre, Its pretty simple,
take a wire
and clip it onto the quadrant
where the ground wires
connect , or to the
copper ground strap in the bilge , then
connect the wire to one side of a multi meter ,
say the
black lead and then place the red
lead on the zincs on your
rudder . You of
course have to set your meter to the
continuity setting , its simple , have someone
that knows
how to use a meter show you or
follow instructions provided
with your
meter.If you have continuity your meter will beep
and the numbers change. While its vital that
you have
continuity , as I have just
learned , that does not mean
that you have
adequate continuity. While you are in the
water you can have the potential checked which
gives you a
better picture of the state of
protection. Don't ask me
to explain
potential , I only have a foggy idea of what it
means and could not put it into words.

Hope this helps,

Pat SM123

Good morning
Pat,





Thanks for
sharing the information.





Please forgive my ignorance,
but how do you measure the
continuity…


I hate to
admit it, I didn’t know about it when I did the
last haul out in March 2015, I then read on the
forum and
the owner manual.


And will
definitely want to do it next year.


But how do you do it?
(pictures rather than words would be
so
nice)…





I assume you can only do it on land.





Sincerely,
Alexandre

Before my boat went into back
into the


water yesterday , I checked for continuity
between the


copper strap and the zincs and I did have
continuity.
Later


, I had two marine
electricians on the boat and they
checked


the potential
from the quadrant and found it to be only
560


, they tell me that they would expect to see
about 900.
900


would insure that the zincs
are protecting the metal
parts


of the boat.
We can only speculate that the connection


between the
quadrant wire and the zincs have been degraded
.


There may not be enough contact between the
zinc bolt
and


the strap inside  the rudder
, it would only be the


threaded area of the bolt and the strap , and
stainless
is


not the best metal as a
conductor . Bottom line is that
I


need more
zinc protection/contact. They suggested that
we


install a large zinc on the hull with two
bronze bolts (


better conductivity )through the hull , wired
directly
to


the strap in the bilge. I am
writing this to inform the


group , that just because you
have continuity , does
not


mean that you
have adequate contact/protection.

Now that is an interesting concept, it would definately solve the problem. Thank you Craig.

Mike, The strap is connected to the connection at the quadrant , which in turn is connected to the zincs, that's my understanding.

Hi Pat,
So what is the bilge ground strap connected to? I suppose the iron keel?  Should we be looking at the continuity between the keel and the zincs?

Alexandre, Sorry I missed the second part of your question. I would check it at the strap in the bilge , that way it also confirms that you have continuity between the strap and the quadrant connection . That's actually what its all about , confirming contact between the ground strap in the bilge and the zincs on your rudder.
Pat

Good morning Pat,

The way you describe it sounds very simple… at the next haul it will do that and you mentioned the number should be 900 (?)
Do you have to check several items? quadrant then ground copper strap in the bilge or 1 is enough?

Thanks again.
Sincerely, Alexandre

Alexandre, Its pretty simple, take a wire
and clip it onto the quadrant where the ground wires
connect , or to the copper ground strap in the bilge , then
connect the wire to one side of a multi meter , say the
black lead and then place the red lead on the zincs on your
rudder . You of course have to set your meter to the
continuity setting , its simple , have someone that knows
how to use a meter show you or follow instructions provided
with your meter.If you have continuity your meter will beep
and the numbers change. While its vital that you have
continuity , as I have just learned , that does not mean
that you have adequate continuity. While you are in the
water you can have the potential checked which gives you a
better picture of the state of protection. Don't ask me
to explain potential , I only have a foggy idea of what it
means and could not put it into words.

Hope this helps,

Pat SM123

Good morning Pat,





Thanks for sharing the information.





Please forgive my ignorance, but how do you measure the
continuity…


I hate to admit it, I didn’t know about it when I did the
last haul out in March 2015, I then read on the forum and
the owner manual.


And will definitely want to do it next year.


But how do you do it? (pictures rather than words would be
so nice)…





I assume you can only do it on land.

Before my boat went into back into the


water yesterday , I checked for continuity between the


copper strap and the zincs and I did have continuity.
Later


, I had two marine electricians on the boat and they
checked


the potential from the quadrant and found it to be only
560


, they tell me that they would expect to see about 900.
900


would insure that the zincs are protecting the metal
parts


of the boat. We can only speculate that the connection


between the quadrant wire and the zincs have been degraded
.


There may not be enough contact between the zinc bolt
and


the strap inside  the rudder , it would only be the


threaded area of the bolt and the strap , and stainless
is


not the best metal as a conductor . Bottom line is that
I


need more zinc protection/contact. They suggested that
we


install a large zinc on the hull with two bronze bolts (


better conductivity )through the hull , wired directly
to


the strap in the bilge. I am writing this to inform the


group , that just because you have continuity , does
not


mean that you have adequate contact/protection.

Thank you Erik,
I think I found it:
http://www.boatzincs.com/corrosion-reference-electrode-specs.html

Do you use it yourself?

Degraded continuity    Alexandre, The number
900 refers to potential, which is also measured using a
multi meter , but you also have to have a silver cathode ,
expensive. It would probably be best for you to have a
marine electrician perform that measurement  if you are not
familiar with multi meters . It would not take them but a
few minutes. Just measuring that you have continuity , you
would just listen for the beep , the number will also change
from 0 to 1 or 1 to 0 ,I cannot remember , just listen for
the beep.Pat SM123

The way you describe it sounds
very simple… at the next haul it will do that and you
mentioned the number should be 900 (?)
Do
you have to check several items? quadrant then ground copper
strap in the bilge or 1 is enough?

Thanks again.

Alexandre, Its pretty simple,
take a wire
and clip it onto the quadrant
where the ground wires
connect , or to the
copper ground strap in the bilge , then
connect the wire to one side of a multi meter ,
say the
black lead and then place the red
lead on the zincs on your
rudder . You of
course have to set your meter to the
continuity setting , its simple , have someone
that knows
how to use a meter show you or
follow instructions provided
with your
meter.If you have continuity your meter will beep
and the numbers change. While its vital that
you have
continuity , as I have just
learned , that does not mean
that you have
adequate continuity. While you are in the
water you can have the potential checked which
gives you a
better picture of the state of
protection. Don't ask me
to explain
potential , I only have a foggy idea of what it
means and could not put it into words.

Hope this helps,

Pat SM123

Good morning
Pat,





Thanks for
sharing the information.





Please forgive my ignorance,
but how do you measure the
continuity…


I hate to
admit it, I didn’t know about it when I did the
last haul out in March 2015, I then read on the
forum and
the owner manual.


And will
definitely want to do it next year.


But how do you do it?
(pictures rather than words would be
so
nice)…





I assume you can only do it on land.





Sincerely,
Alexandre

Before my boat went into back
into the


water yesterday , I checked for continuity
between the


copper strap and the zincs and I did have
continuity.
Later


, I had two marine
electricians on the boat and they
checked


the potential
from the quadrant and found it to be only
560


, they tell me that they would expect to see
about 900.
900


would insure that the zincs
are protecting the metal
parts


of the boat.
We can only speculate that the connection


between the
quadrant wire and the zincs have been degraded
.


There may not be enough contact between the
zinc bolt
and


the strap inside  the rudder
, it would only be the


threaded area of the bolt and the strap , and
stainless
is


not the best metal as a
conductor . Bottom line is that
I


need more
zinc protection/contact. They suggested that
we


install a large zinc on the hull with two
bronze bolts (


better conductivity )through the hull , wired
directly
to


the strap in the bilge. I am
writing this to inform the


group , that just because you
have continuity , does
not


mean that you
have adequate contact/protection.

Thank you Erik,
I think I found it:
http://www.boatzincs.com/corrosion-reference-electrode-specs.html

Do you use it yourself?

Sincerely, Alexandre

The silver electrode is
available from boatzincs.com it is about $120-
US.  Fair

Degraded continuity    Alexandre, The number
900 refers to potential, which is also measured using a
multi meter , but you also have to have a silver cathode ,
expensive. It would probably be best for you to have a
marine electrician perform that measurement  if you are not
familiar with multi meters . It would not take them but a
few minutes. Just measuring that you have continuity , you
would just listen for the beep , the number will also change
from 0 to 1 or 1 to 0 ,I cannot remember , just listen for
the beep.Pat SM123

continuity  Good morning Pat,

The way you describe it sounds
very simple… at the next haul it will do that and you
mentioned the number should be 900 (?)
Do
you have to check several items? quadrant then ground copper
strap in the bilge or 1 is enough?

Thanks again.

Alexandre, Its pretty simple,
take a wire
and clip it onto the quadrant
where the ground wires
connect , or to the
copper ground strap in the bilge , then
connect the wire to one side of a multi meter ,
say the
black lead and then place the red
lead on the zincs on your
rudder . You of
course have to set your meter to the
continuity setting , its simple , have someone
that knows
how to use a meter show you or
follow instructions provided
with your
meter.If you have continuity your meter will beep
and the numbers change. While its vital that
you have
continuity , as I have just
learned , that does not mean
that you have
adequate continuity. While you are in the
water you can have the potential checked which
gives you a
better picture of the state of
protection. Don't ask me
to explain
potential , I only have a foggy idea of what it
means and could not put it into words.

Hope this helps,

Pat SM123

Good morning
Pat,





Thanks for
sharing the information.





Please forgive my ignorance,
but how do you measure the
continuity…


I hate to
admit it, I didn’t know about it when I did the
last haul out in March 2015, I then read on the
forum and
the owner manual.


And will
definitely want to do it next year.


But how do you do it?
(pictures rather than words would be
so
nice)…





I assume you can only do it on land.





Sincerely,
Alexandre

Before my boat went into back
into the


water yesterday , I checked for continuity
between the


copper strap and the zincs and I did have
continuity.
Later


, I had two marine
electricians on the boat and they
checked


the potential
from the quadrant and found it to be only
560


, they tell me that they would expect to see
about 900.
900


would insure that the zincs
are protecting the metal
parts


of the boat.
We can only speculate that the connection


between the
quadrant wire and the zincs have been degraded
.


There may not be enough contact between the
zinc bolt
and


the strap inside  the rudder
, it would only be the


threaded area of the bolt and the strap , and
stainless
is


not the best metal as a
conductor . Bottom line is that
I


need more
zinc protection/contact. They suggested that
we


install a large zinc on the hull with two
bronze bolts (


better conductivity )through the hull , wired
directly
to


the strap in the bilge. I am
writing this to inform the


group , that just because you
have continuity , does
not


mean that you
have adequate contact/protection.

Alexandre, The number 900 refers to potential, which is also measured using a multi meter , but you also have to have a silver cathode , expensive. It would probably be best for you to have a marine electrician perform that measurement  if you are not familiar with multi meters . It would not take them but a few minutes. Just measuring that you have continuity , you would just listen for the beep , the number will also change from 0 to 1 or 1 to 0 ,I cannot remember , just listen for the beep.

Good morning Pat,

The way you describe it sounds very simple… at the next haul it will do that and you mentioned the number should be 900 (?)
Do you have to check several items? quadrant then ground copper strap in the bilge or 1 is enough?

Thanks again.
Sincerely, Alexandre

Alexandre, Its pretty simple, take a wire
and clip it onto the quadrant where the ground wires
connect , or to the copper ground strap in the bilge , then
connect the wire to one side of a multi meter , say the
black lead and then place the red lead on the zincs on your
rudder . You of course have to set your meter to the
continuity setting , its simple , have someone that knows
how to use a meter show you or follow instructions provided
with your meter.If you have continuity your meter will beep
and the numbers change. While its vital that you have
continuity , as I have just learned , that does not mean
that you have adequate continuity. While you are in the
water you can have the potential checked which gives you a
better picture of the state of protection. Don't ask me
to explain potential , I only have a foggy idea of what it
means and could not put it into words.

Hope this helps,

Pat SM123

Good morning Pat,





Thanks for sharing the information.





Please forgive my ignorance, but how do you measure the
continuity…


I hate to admit it, I didn’t know about it when I did the
last haul out in March 2015, I then read on the forum and
the owner manual.


And will definitely want to do it next year.


But how do you do it? (pictures rather than words would be
so nice)…





I assume you can only do it on land.

Before my boat went into back into the


water yesterday , I checked for continuity between the


copper strap and the zincs and I did have continuity.
Later


, I had two marine electricians on the boat and they
checked


the potential from the quadrant and found it to be only
560


, they tell me that they would expect to see about 900.
900


would insure that the zincs are protecting the metal
parts


of the boat. We can only speculate that the connection


between the quadrant wire and the zincs have been degraded
.


There may not be enough contact between the zinc bolt
and


the strap inside  the rudder , it would only be the


threaded area of the bolt and the strap , and stainless
is


not the best metal as a conductor . Bottom line is that
I


need more zinc protection/contact. They suggested that
we


install a large zinc on the hull with two bronze bolts (


better conductivity )through the hull , wired directly
to


the strap in the bilge. I am writing this to inform the


group , that just because you have continuity , does
not


mean that you have adequate contact/protection.

Re: [Amel Yacht Owners] Degraded continuity

Hi Pat,

So what is the bilge ground strap connected to? I suppose the iron keel?  Should we be looking at the continuity between the keel and the zincs?

Alexandre, Sorry I missed the second part of your question. I would check it at the strap in the bilge , that way it also confirms that you have continuity between the strap and the quadrant connection . That's actually what its all about , confirming contact between the ground strap in the bilge and the zincs on your rudder.

Good morning Pat,

The way you describe it sounds very simple… at the next haul it will do that and you mentioned the number should be 900 (?)
Do you have to check several items? quadrant then ground copper strap in the bilge or 1 is enough?

Thanks again.
Sincerely, Alexandre

Alexandre, Its pretty simple, take a wire
and clip it onto the quadrant where the ground wires
connect , or to the copper ground strap in the bilge , then
connect the wire to one side of a multi meter , say the
black lead and then place the red lead on the zincs on your
rudder . You of course have to set your meter to the
continuity setting , its simple , have someone that knows
how to use a meter show you or follow instructions provided
with your meter.If you have continuity your meter will beep
and the numbers change. While its vital that you have
continuity , as I have just learned , that does not mean
that you have adequate continuity. While you are in the
water you can have the potential checked which gives you a
better picture of the state of protection. Don't ask me
to explain potential , I only have a foggy idea of what it
means and could not put it into words.

Hope this helps,

Pat SM123

Good morning Pat,





Thanks for sharing the information.





Please forgive my ignorance, but how do you measure the
continuity…


I hate to admit it, I didn’t know about it when I did the
last haul out in March 2015, I then read on the forum and
the owner manual.


And will definitely want to do it next year.


But how do you do it? (pictures rather than words would be
so nice)…





I assume you can only do it on land.

Before my boat went into back into the


water yesterday , I checked for continuity between the


copper strap and the zincs and I did have continuity.
Later


, I had two marine electricians on the boat and they
checked


the potential from the quadrant and found it to be only
560


, they tell me that they would expect to see about 900.
900


would insure that the zincs are protecting the metal
parts


of the boat. We can only speculate that the connection


between the quadrant wire and the zincs have been degraded
.


There may not be enough contact between the zinc bolt
and


the strap inside  the rudder , it would only be the


threaded area of the bolt and the strap , and stainless
is


not the best metal as a conductor . Bottom line is that
I


need more zinc protection/contact. They suggested that
we


install a large zinc on the hull with two bronze bolts (


better conductivity )through the hull , wired directly
to


the strap in the bilge. I am writing this to inform the


group , that just because you have continuity , does
not


mean that you have adequate contact/protection.

Thanks for all the information Pat, including the silver cathode.
I heard Kent mentioning this, but was not sure of the use.
Sincerely, Alexandre

Alexandre, Sorry I missed the second part of
your question. I would check it at the strap in the bilge ,
that way it also confirms that you have continuity between
the strap and the quadrant connection . That's actually
what its all about , confirming contact between the ground
strap in the bilge and the zincs on your rudder.

Pat

Good morning Pat,





The way you describe it sounds very simple… at the next
haul it will do that and you mentioned the number should be
900 (?)


Do you have to check several items? quadrant then ground
copper strap in the bilge or 1 is enough?





Thanks again.


Sincerely, Alexandre

Alexandre, Its pretty simple, take a wire


and clip it onto the quadrant where the ground wires


connect , or to the copper ground strap in the bilge ,
then


connect the wire to one side of a multi meter , say the


black lead and then place the red lead on the zincs on
your


rudder . You of course have to set your meter to the


continuity setting , its simple , have someone that
knows


how to use a meter show you or follow instructions
provided


with your meter.If you have continuity your meter will
beep


and the numbers change. While its vital that you have


continuity , as I have just learned , that does not
mean


that you have adequate continuity. While you are in the


water you can have the potential checked which gives you
a


better picture of the state of protection. Don't ask
me


to explain potential , I only have a foggy idea of what
it


means and could not put it into words.





Hope this helps,





Pat SM123

Good morning Pat,

















Thanks for sharing the information.

















Please forgive my ignorance, but how do you measure the


continuity…








I hate to admit it, I didn’t know about it when I did
the


last haul out in March 2015, I then read on the forum
and


the owner manual.








And will definitely want to do it next year.








But how do you do it? (pictures rather than words would
be


so nice)…

















I assume you can only do it on land.

Before my boat went into back into the








water yesterday , I checked for continuity between the








copper strap and the zincs and I did have continuity.


Later








, I had two marine electricians on the boat and they


checked








the potential from the quadrant and found it to be only


560








, they tell me that they would expect to see about 900.


900








would insure that the zincs are protecting the metal


parts








of the boat. We can only speculate that the connection








between the quadrant wire and the zincs have been
degraded


.








There may not be enough contact between the zinc bolt


and








the strap inside  the rudder , it would only be the








threaded area of the bolt and the strap , and stainless


is








not the best metal as a conductor . Bottom line is that


I








need more zinc protection/contact. They suggested that


we








install a large zinc on the hull with two bronze bolts
(








better conductivity )through the hull , wired directly


to








the strap in the bilge. I am writing this to
inform the








group , that just because you have continuity , does


not








mean that you have adequate contact/protection.

Re: [Amel Yacht Owners] Degraded continuity

Patrick McAneny
 

Alexandre, Sorry I missed the second part of your question. I would check it at the strap in the bilge , that way it also confirms that you have continuity between the strap and the quadrant connection . That's actually what its all about , confirming contact between the ground strap in the bilge and the zincs on your rudder.

Good morning Pat,

The way you describe it sounds very simple… at the next haul it will do that and you mentioned the number should be 900 (?)
Do you have to check several items? quadrant then ground copper strap in the bilge or 1 is enough?

Thanks again.
Sincerely, Alexandre

Alexandre, Its pretty simple, take a wire
and clip it onto the quadrant where the ground wires
connect , or to the copper ground strap in the bilge , then
connect the wire to one side of a multi meter , say the
black lead and then place the red lead on the zincs on your
rudder . You of course have to set your meter to the
continuity setting , its simple , have someone that knows
how to use a meter show you or follow instructions provided
with your meter.If you have continuity your meter will beep
and the numbers change. While its vital that you have
continuity , as I have just learned , that does not mean
that you have adequate continuity. While you are in the
water you can have the potential checked which gives you a
better picture of the state of protection. Don't ask me
to explain potential , I only have a foggy idea of what it
means and could not put it into words.

Hope this helps,

Pat SM123

Good morning Pat,





Thanks for sharing the information.





Please forgive my ignorance, but how do you measure the
continuity…


I hate to admit it, I didn’t know about it when I did the
last haul out in March 2015, I then read on the forum and
the owner manual.


And will definitely want to do it next year.


But how do you do it? (pictures rather than words would be
so nice)…





I assume you can only do it on land.

Before my boat went into back into the


water yesterday , I checked for continuity between the


copper strap and the zincs and I did have continuity.
Later


, I had two marine electricians on the boat and they
checked


the potential from the quadrant and found it to be only
560


, they tell me that they would expect to see about 900.
900


would insure that the zincs are protecting the metal
parts


of the boat. We can only speculate that the connection


between the quadrant wire and the zincs have been degraded
.


There may not be enough contact between the zinc bolt
and


the strap inside  the rudder , it would only be the


threaded area of the bolt and the strap , and stainless
is


not the best metal as a conductor . Bottom line is that
I


need more zinc protection/contact. They suggested that
we


install a large zinc on the hull with two bronze bolts (


better conductivity )through the hull , wired directly
to


the strap in the bilge. I am writing this to inform the


group , that just because you have continuity , does
not


mean that you have adequate contact/protection.
