Re: old Maramu - considering painted bulkheads in toilet compartments

Alejandro Paquin
 

Dave;
We decided to change all the headliner and original material on the boat. It is a dreadful job. Joel Potter wrote on this sometime ago and issued some stern warnings.
We discovered that the surface is highly irregular and "transparent" in some places. The material we used now has a light padding, hopefully it will last 15 more years and never need replacing again in my lifetime. I doubt painting is an option.
In the cockpit and aft cabin the new liner is now "floating", not glued directly to the surface. We used thin strips of wood as a base, screwed to the fiberglass using short SS screws. The liner is SS stapled to these strips in a way that we used the original wood trimming to conceal the staples. This is all hard work and requires lots of patience and detail. It is important to note that we also replaced all the crazed plexiglass in all hatches and side port lights, which requires the inside plywood panels to be removed as well. These cover the headliner edges around the port lights.
Now the heads: we will apply a more neutral gelcoat in the floor pans and will change the green and orange carpet lining the shelves. We also changed the formica on the shelve cover panel. believe me this is a huge project and has consumed 6 months.

Like so many older Amel sailboats, the vinyl headliners are failing in several places. In the toilet compartments we are considering just painting the bulkheads.

Before we remove the vinyl, I thought it would be good to ask if anyone has painted as opposed to replacing the vinyl. If so, was there a lot of work involved in getting the surface smooth enough for paint?

As part of this project we are going to repaint the fiberglass floor pans in the toilet compartments. Our boat, formerly owned by Henri Amel himself, is a bit different than others we've seen in that the floor pan in the forward toilet compartment is orange and the aft one is green. The yard also used different color carpet on the shelves. We don't know if Henri suggested they just use remnants or if that was the desired appearance.

Hi all be very careful regarding engine rpm's over or under will change the voltage an Hz out put that may do other damage. Note the run position of the lever and mark it. You may also want to use a tachometer to test and set.

All,

There is some missing information in this thread because there were some private emails exchanged between myself and Alessandro.

I am sure that there are a few of you that would like to see that exchange, so I have pasted it here:

FROM ALESSANDRO TO BEBE:
Thank so much...I 'd try a new (fuel) pump BUT when Onan stopped no flashing code appears...
This is a strange thing!

FROM BEBE TO ALESSANDRO:
One more thing I thought of for a shutdown without a code:

Try this:
Go to the fuel injection pump and you should see a little lever that gets pulled by a small solenoid. That solenoid may be going bad. See if the solenoid is pulling or dropping out when the engine starts, then shut down.

This solenoid has two coils. One is 12VDC for starting and the other is 4VDC which holds the solenoid after starting. The 4 volt coil may be going bad. When you hold the start button down, the alarms are bypassed and the 12VDC coil on the solenoid is energized. When you release the start button, the 4VDC coil on the solenoid is energized and keeps the solenoid closed.

Try holding the lever with your hand, or mechanically keeping it in a "run position" by tying or wiring it in position. If the Onan continues to run, you need to replace this solenoid. I believe that if this solenoid fails you will receive no code.

Additionally, regarding the impeller blades:
If you did not get a shutdown code, the impeller was probably not the source of your shutdown because if your shutdown was due to overheating or lack of water flow, you would see a flashing code.

The best way that I have found to simply remove all of the impeller blades from the Onan Heat Exchanger is to close the main sea chest valve and open the end caps on both ends of the Heat Exchanger...while using a wet/dry shop vacuum (shop-vac) to suck the excess water and the blade parts which will end up in the vacuum. If you turn on the shop-vac as you loosen the end caps, you will capture all of the water and have zero water clean-up.

This would also be a great time to change the zinc on the Heat Exchanger.

Unfortunately, if you do not have a wet/dry shop-vac, you will need to remove the Heat Exchanger to get all of the pieces out. Removing the Exchanger is problematic with all of its connections, so buy or borrow a shopvac. Also, the end caps and end cap gaskets are delicate and may get damaged in this process. It is a good idea to keep end cap spares on-board.

Hope this solves your problem...let me know.

I have never got more than 120 hours from a genuine Onan impeller they need to be inspected and changed often.

After checking the error code displayed by the number of flashes on the

broken parts of the impellor out of the salt water side of the cooling

exchanger. If not, you must go through the system and get all the pieces as
they will impede water flow and cause enough of a slight overheat/reduced
water flow condition to shut the unit down after about a half hour. It is
important when removing the impellor to count the blades THAT ARE MISSING

Alessandro,
quando hai controllato il Racor sembrava ok, ma l'hai anche sostituto ?
E' meglio farlo ogni 50/70 ore. Lo Yanmar ha una pompa forte, mentre quella dell'Onan è più debole.
Se hai dubbi fai partire l'Onan è controlla la lancetta del manometro. Se vibra vuol dire che è il filtro Racor. Regge per un pò e poi si spegne.
Un'altra ragione di fermo inaspettato ,che a me è successo , può dipendere dall'interferenza con la radio HF in trasmissione. Il pulsante di STOP parte da solo, incredibile !
Ma dipende da come è installata la radio e comunque non mi sembra il caso tuo.
Fammi sapere se credi direttamente al mio indirizzo.
" I suggest to replace the racor filter if the gauge arrow begins to vibrate : the Onan starts but after a while stops."

What error code are you getting? The error code is a series of blinking lights on the start switch.

From your description I would guess that the Onan is either starving for fuel, or there is a faulty 12VDC connection.

A few things to consider in order of priority:
If the electric fuel pump is failing, it could intermittently deliver insufficient pressure and starve the Onan of fuel. Be sure that the fuel pump is operating correctly before going to the next step. BTW, the electric fuel pump will eventually fail. If you do not have a spare, now is the time to buy one to determine if this is your problem. If you have a problem with a new one installed, proceed to the next step which will be much more difficult. If the new fuel pump works for you, buy a second one for a spare, if you plan to cross additional oceans.

The Onan will shut down if the 12VDC current is interrupted for even 1 second. This includes both the ground and positive wire. Generally the most suspect parts for intermittent 12VDC current faults are the positive and the negative solenoids.

Re: [Amel] Strange problem with ONAN

One more thing I thought of for a shutdown without a code:

Try this:
Go to the fuel injection pump and you should see a little lever that gets pulled by a small solenoid. That solenoid may be going bad. See if the solenoid is pulling or dropping out when the engine starts, then shut down.

This solenoid has two coils. One is 12VDC for starting and the other is 4VDC which holds the solenoid after starting. The 4 volt coil may be going bad. When you hold the start button down, the alarms are bypassed and the 12VDC coil on the solenoid is energized. When you release the start button, the 4VDC coil on the solenoid is energized and keeps the solenoid closed.

Try holding the lever with your hand, or mechanically keeping it in a "run position" by tying or wiring it in position. If the Onan continues to run, you need to replace this solenoid. I believe that if this solenoid fails you will receive no code.

Additionally, regarding the impeller blades:
If you did not get a shutdown code, the impeller was probably not the source of your shutdown because if your shutdown was due to overheating or lack of water flow, you would see a flashing code.

The best way that I have found to simply remove all of the impeller blades from the Onan Heat Exchanger is to close the main sea chest valve and open the end caps on both ends of the Heat Exchanger...while using a wet/dry shop vacuum (shop-vac) to suck the excess water and the blade parts which will end up in the vacuum. If you turn on the shop-vac as you loosen the end caps, you will capture all of the water and have zero water clean-up.

This would also be a great time to change the zinc on the Heat Exchanger.

Unfortunately, if you do not have a wet/dry shop-vac, you will need to remove the Heat Exchanger to get all of the pieces out. Removing the Exchanger is problematic with all of its connections, so buy or borrow a shopvac. Also, the end caps and end cap gaskets are delicate and may get damaged in this process. It is a good idea to keep end cap spares on-board.

Hope this solves your problem...let me know.

I just crossed atlantic and during passage Onan worked perfectly for 6h/day
for 15days but the 16th day began to "cough" and stopped: I check Racor were
ok, I changed fuel filter, But I found impeller broker and so I changed it!
BUT, anyway, after that my ONAN works well for just 20 minutes than starts
"coughing" and stops! Now I''m in St lucia and here mechanic can't solve the

Re: Strange problem with ONAN

Alessandro,

What error code are you getting? The error code is a series of blinking lights on the start switch.

From your description I would guess that the Onan is either starving for fuel, or there is a faulty 12VDC connection.

A few things to consider in order of priority:
If the electric fuel pump is failing, it could intermittently deliver insufficient pressure and starve the Onan of fuel. Be sure that the fuel pump is operating correctly before going to the next step. BTW, the electric fuel pump will eventually fail. If you do not have a spare, now is the time to buy one to determine if this is your problem. If you have a problem with a new one installed, proceed to the next step which will be much more difficult. If the new fuel pump works for you, buy a second one for a spare, if you plan to cross additional oceans.

The Onan will shut down if the 12VDC current is interrupted for even 1 second. This includes both the ground and positive wire. Generally the most suspect parts for intermittent 12VDC current faults are the positive and the negative solenoids.

Check out "Onan DC Control Schema" at http://groups.yahoo.com/group/amelyachtowners/photos/album/1489622282/pic/list?mode=tn&order=ordinal&start=1&dir=asc

Hope this helps. Please let me know what you find.

Merry Christmas fellow Amel owners!

I would be very grateful if someone could help me with this please. I recently had a small fire in my shore power plug and it melted most of the connections. Luckily, it was limited to just the plug and no other damage was incurred. I purchased a replacement plug (Marinco 50A 125/250v part number 6365CRN) and thought this would be an easy swap out. Ha!

In the shore power cord, I have 4 wires: Red, Black, White and BLUE. I can see from the old installation that white goes to white (W), red goes to red (X) and black goes to black (Y). My problem is the instructions call for a green wire to connect to green (G). I have a blue wire. Is this the same as the green wire?????

I should probably tell you I am in the USA at this point and need to configure to the marina 50a 220v service.

I can't be sure where the blue wire was connected, if it was connected at all, since most of the plug has melted on this side. I have four wires and four holes. Logic tells me to connect the blue to the green slot but I figured it doesn't hurt to ask. I really like our boat and would like not to blow it up this Christmas.

Thanks in advance for the help!

Mystery solved! Apparently the teal wire is green. I connected the wire and turned off everything except the outlets and used a meter and the on board 8247 Multi-Meter Blue Sea System to determine all was wired correctly.
Nothing blew up and Cream Puff lived to see another day

Upon closer inpection here, this wire is a teal color (neither green or blue)

Also, this may not be the orginal factory shore power cord as the previous owner had a Charles Marine Isolation Transformer installed.

Thoughts?
