Craig,

 

I cannot speak to other models, but in the factory handover of the 55, they made it clear to fire the genset and both chargers prior to starting docking maneuvers.  I am not on the boat now, but believe I have also seen that instruction in the owners manual.

I just looked on my 55 and there is a 675A master fuse under the nav seat. I used my Fluke to measure the current coming out of that fuse and the bow thruster doesn't draw power from there when I ran it which surprises me but the Fluke doesn't lie. So, there must be another 24V run to the sail locker. I'll try again tonight and measure the current up there instead.

Hi Mitchell,

Thanks!!
We never had the oil seal...we have taken it apart many times in the 20 years we have her...that is unless it was removed before we bought her....:/
It would be a great help though if you could point it out for us on the plans.
We always managed to make the seal with just the gasket maker.... the fibreglass trumpet is not in a good condition anymore, perhaps that’s the problem!
Did you make any repairs to that?

Best regards,

Hi Helen,

I miss read what you were doing. I thought you were referring to the lower unit.

As far as your oil leak goes. There is a 85x110x12mm oil seal with stainless steel spring at the top of the lower unit where the trumpet looking fibreglass thing marries with the lower unit. I believe this oil seal is designed to retain the oil, should this leak as a backup you have the silicone gasket you are using where the upper unit is bolted to the fibreglass trumpet looking thing. I would guess this oil seal has been dislodged or damaged when the upper unit was repaired/ reinstalled.

The lower unit needs to be removed to replace this seal. This is not a difficult task once you have the upper unit off but the boat obviously has to be out of the water.

For economy I just replaced the oil with engine oil as originally recommend by Amel. When examined all gears top and bottom had very little where so I believe engine oil is sufficient to use in this light application. It is my opinion damage caused to these units is most likely often from miss aligned engines rather then anything to do with oil grade.


Let me know if it is unclear where the oil seal is located and I will mark it up on the plan.

Our fibreglass did not have the aluminium part, at least not since we have the boat, we have taken it apart many times in the 20 years we have her, probably Amel made the change after our hull.
We changed all the bearings and gears in the upper part, but didn’t touch the lower.
Have you changed the viscosity of the oil you use or do you still use the 15W 40?

Should we try to find card to cut a gasket or try again with the RTV gasket maker? The fibreglass part is not in a very good condition.

Hi Ken,
While you say, "Thank you Bill (Rouse) for a fact I didn't know, and I don't think that most Amel owners were aware of: That Amel suggests owners to run the genset every time the bow thruster is used.", Amel absolutely did not suggest that to SN owners regarding their bow thrusters. Frankly, I kinda wonder about it for other models, too. If I'm using the BT for a long time (like fighting a cross wind)  I may rev up the engine in neutral but not for just nudging into a slip with short bursts. I would posit that the boats are designed to be able to use the BT for normal docking without having to run the genset.
Cheers, Craig

Re: Masse negative leak

Thanks Bill,

Alas it is not the Macerators. I hate working in the space for the main battery on/off as it is so easy to short out the positive to negative with a ratchet handle... maybe I can cover the positive with plastic sheet or something...

Ofer & Nick,

Remember, the minus Masse Light means there is a connection between 24-volts negative to the Amel bonding system. The most common issue is a Jabsco Macerator pump that has developed a leak at the seal, causing a connection to the Amel Bonding. Start by disconnecting the green/yellow wire from each macerator pump. If the light no longer comes ON, you have found it. Replace that macerator pump and reconnect the green/yellow wires.

If it was not the macerator pump and the light is ON for the (-) side, it is more difficult because the individual 24-volt breakers only turn OFF the positive side (+). For a negative side (-) Masse fault, you will need to disconnect the negative wires from the negative main battery switch. On most Amels, this is the lower switch. When the light goes out, you have narrowed your search to one main circuit.

If the (+) side is ON, try turning OFF each breaker throughout the boat one at a time. Don't forget breakers for the windlass, winches, and breakers in the engine room. Do this with all breakers.

I hope this helps you.

Hi Nick,
We had the same problem.
It took long time to solve , because the light was not always ON.

The way to find where  a bad contact between the minus and the grounding system is, is to start from the main switches near the batteries, disconnect each of the cables while checking the light. Ones you find a cable that if  disconnected the is OFF, look for the equipment down the cable and check the contacts and put corrosion x.
We found the problem in the forward locker . We had a leak of water from the new Bad! installed windlass rubber deck switches that created humidity on all electrical motors in the locker.

Good luck with the challenge.

Re: A 55 # 9 : Chargeing and mastershunts

Ken Powers SV Aquarius
 

Arno, and Bill,

The fact is that large current draws on your batteries will kill them faster.  Yes, a battery can supply a lot of current, but if you use this capability you shorten their life over time.   During large current draws Arno suggests that all the batteries are equally suppling their %, but I might suggest that not all the batteries are created equal, some pairs may be supplying 110Amps and others much less.  Just like pallbearers, not all hands are supplying the same force.  

Thank you Bill for a fact I didn't know, and I don't think that most Amel owners were aware of:  That Amel suggests owners to run the genset every time the bow thruster is used.   Running the Genset does makes sense given the amount of current required for the bow thruster, and it also implies that Amel is, and was aware, that the bow thruster draw could be too high for the batteries alone.  

But, these responses do not Answer the original QUESTION;  Why are two 500Amp shunts on the A55?
And it does not Answer my question which I think will shed some light on the original question:  How many Amps the A55 Bow thruster draws?

The original question, about the A55 battery electronics going into shut down, then coming back online after a few seconds.  This is actually how I would think the electronics on a good Amel with bad batteries should work.  If you bring the voltage on your 24V batteries below 24V the Amel should go into shut down to protect the batteries ( The owner probably even has the capability to set the shut down voltage).  Then a few seconds, after the voltage increases above 24V (or what ever voltage was set for shutdown), the electronics should turn the 24V house power back on.  

Personally I would also like to know the current draw others are seeing on their Amel's.  We draw about 400Amps when we light up the bow "thirsty" thruster. 


PS:  Arno, I had 4 pairs of batteries in my SM battery compartment, the A54 or the A55 might have a bigger compartment which fits 6 pairs.  I tried to fit 5 pairs, but they didn't fit (I had Vicron 110AH AGM's 8 pieces in my battery bank).  So, on Aquarius I was looking at 400 Amps / 4 pairs = 100Amps per pair if everything being equal (which never is).   I believe that's about the MAX for my old batteries.

In a previous post I recall Joel Potter confirmed that the SN and the SM had the same rub rail (SN shorter, of course). I just reread his post and he says the Maramu is different.
I see that the company you got, Techno Rubber Industries in Miami, manufactures inflatable boat rub rails for some of the big brands, or perhaps, just supplies replacements for them (they are showing the logos of Avon, Zodiac, etc. on their web page). Sounds like a great choice.
