Please take note 28.4 bolts is not over charging a large 24 volt system. Second when the new smart chargers see max voltage they move to float. Second as you are motoring you are also using a rather amp hungry group if this and that on board so the alternator also needs to keep up with those. Third a smart charger will normally and a heat sensor that tells the smart charger when the bank is to hot. When it sees over heating it goes to float.

In any case the sooner you go with a modern smart charger that is equal in output to at least 10% of the AMP hours of the bank the better.

The 170Amp alternator on our engine is internally regulated to 28.4 volts. So it outputs whatever current it can at 28.4 volts all the time. If you motor for long periods of time this will overcharge the batteries...and could lead to boiling off the electrolyte.
I'm looking at changing this system to have an externally 3 stage regulator that will bulk, absorb and then float. I don't think this internal reg is good for deep cycle batteries.
I contacted Leece-Neville about this and it is not so simple to change as my alt. is regulated on the negative side so its not just a matter of taking out the internal reg and connecting the brushes to the field excitation from the external reg. There's some serious rewiring involved.

Kent,

It was on a boat that was not an Amel. (I am a Jeanneau owner, but follow this list because you have some interesting topics) The Freedom inverter/charger had a sensing line wired directly to the batteries. I have also seen alternator controllers wired like this. It is done to make sure that the voltage that is being sensed is the actual voltage at the battery terminal, and not at the output of the charger. If there are significant losses in the transmission cable from the charger to the battery, the charger could sense an eroneous voltage. Also, if the sensing line has a bad connection it will see the same condition. Connections should be one of the first thing checked when you have a problem like this. Alternatively, use a voltmeter to check the voltage at the charger output and compare that to the voltage at the battery.

When it happened on my boat, my wife was living on board, and the on-board smoke detector kept going off, but there was no sign of smoke or fire in the boat. Turned out that as they overheated, the batteries gave off fumes that set off the smoke detector. If we had waiting longer, the batteries would have gotten so hot they might have started a real fire. It was a close thing.

One very important thing to check is the condition of the voltage sensing line from your batteries back to the charging source, whether it is the alternator or a shore charger. I once had a Freedom charger cook some very nice trojan batteries because the fuse-holder in the sensing line developed a bad connection, and the charger thought that the voltage was lower than it was actually putting out. Very high voltage and boiled batteries. Bad connections can cause this.

Hello

We are owners of a '93 Amel SM and have been trying to find out how to repair the sagging headlining.
At first just a small area in the front cabin of our Amel had vinyl loose and hanging (we're using bullclips as a temporary fix to hold the pieces up). Now there are several areas that are sagging in the main cabin, closets and wc. We have inquired about the problem and it sounds like a major project of taking it all out (requiring screws, panels and various other boat parts to be removed) and redoing it all with new headlining. We have also heard of people getting wood slats to screw in to hold the vinyl up. With this option, how do we clean out all the disintegrated foam/dust that is most likely resting in there without loosening the vinyl further. Where are the best places to screw in the wood panel pieces, what type of wood is best and what width? Also, what type of adhesive is best to reglue the vinyl to the fiberglass ceilings/walls? Any how-to advice would be greatly appreciated. If best to have it professionally done, any recommendations for
someone who can repair the headlining in or near Croatia? Finally, how can we prevent the sagging from occurring again?

Many thanks in advance for any suggestions you may have.

Martin,
I forgot to mention that if you have a Reja pump, you most likely will have to prime it. Take off the hose from the fresh water reservoir and fill it with water, there used to be a bleed bolt on the top of the pump that you need to loosen until the water is free flowing from the reservoir.
Good luck.

Re: Venting fresh water system after complete drain down

Martin,
fill you water tank,open ALL of your fresh water outlets and turn on your water pump
that should clear the air. The accumulator pressure should be preset and the same for the regulator. Once you clear the air and close the taps (it seems to work better on the SM from the aft heads forward) it all should work.
After running the engine, if it over heats, remove the return flow pipe from the hot water heater where it returns to the engine and clear the airlock.
I hope this is of some help.

Re: [Amel] Battery bank problems SM with 13 batteries

Sorry to hear about that Eric. Expensive problem! My Freedom charger/inverter failed last Fall. It overcharged my bank and boiled my 8-battery bank nearly dry. Just lucky I went down to the boat when I did or could have had a fire. It didn't have a temp sensor at the battery bank which would have shut it down. My replacement charger/inverter is a British made Sterling and does have a temp sensor.

As an aside, the Charles IMC smart charger was billed as able to charge both the 24v house bank and the 12v start battery. It has 3 programmable outputs and alternates between them when charging. It nearly boiled the 12v battery dry and read "Failure! Return to manufacturer for service". Charles couldn't assure me that a new one would do any better and sent me new 24v and 12v chargers at no cost. When the batteries are discharged enough to need bulk charge, I turn the 60A Charles and the 60A Sterling and get 100+A going into the batteries until bulk phase is done. When I see <60A going into the batteries I turn one off and finish the charge with only one charger.

I would have your charger tested to make sure it isn't staying in bulk charge mode, as I'm guessing that may be what happened. I didn't realize I had that problem until I charged my new set of batteries and found it charging at 55A when the batteries were at 13.3v.

Hi

1. Even the so called sealed maintenance free batteries need to be checked
from time to time, if they have a way to top the water (as most do). They
are in fact ¨low maintenance¨ ;

2. If you have a voltage regulator, it doesn´t matter if the charger is
small. In fact, the trouble is when you have a charger that is too big for
the bank (about 20 to 25% of the total amperage would be ideal). I guess
you have at least a 600A battery bank, so both the 100 charger and the 175A
nominal alternator would be fine

3. If you do have a voltage regulator, maybe it was set to charge a
different kind of battery. The alternator could also be a suspect, if the
voltage it delivers is out of range, (but it sounds like you don´t use it a
lot).

On our trip home from St Martin last week, we discovered that most of the
liquid in all the sealed maintenance free batteries had boiled off. I did
not realize that under the labels there are plugs where water can be
added.
In any event all the house (12) batteries
have to be replaced.
We have a 175 amp alternator and 30 and 100 amp Dolphin chargers.
I spoke with Dolphin and they said that the 30 amp charger is too small
for the bank and it probably cooked the batteries as it saw the bank as
always needing a charge. I plan on having the alternator checked and then
speak again with Dolphin when I install the new batteries.

Kimberlite usually is in a marina somewhere and plugged in with the 30 amp
charger running.
Any thoughts on my problem?

Hi Eric,
I am sitting in San Carlo Mexico looking at my battery box which has four
very poor Vetus batteries left. They are eighteen months old.
On passage across The Sea of Cortez last week we had exactly the same
problem as you. We have been unable to find twelve deep cycle 105 to 110 amp
hour replacement batteries here and have picked out the best four that we
had left, which are at best,very suspect .
We were running our Yanmar engine @ 2500rpm and after seventy miles or so of
motoring we noticed that horrible sulphur smell, when I checked the battery
box it was very hot and immediately disconnected the alternator drive belts
and turned every electrical 24 volt appliance on.
My thoughts are that we had an open short from overheating in one of the
batteries and it brought down the rest.
The offending battery was at 65C and rising even while disconnected so I
removed it and the other hottest ones from the boat.
Judging from the volume of correspondence in this Forum, Amels do seem
fraught with battery problems, but mostly from over charging with Dolphin
chargers, my chargers are original and seem fine so far. The regulator on
the alternator appears to give out the correct voltage also.
When last in La Rochelle I asked Olivier Beaute should I change to AGM or
gel, his response was a very firm 'NO' . He claimed that Amel really didn't
know why they wouldn't work properly on their boats?
Certainly once overheated they are destroyed. From my own experience the
people that I have met across the Caribbean and Pacific who have had battery
problems all promote Trojan wet cell as the most robust and value for money.
I would welcome if someone could tell me other than drilling a hole into
each battery cell how you actually put water back into a sealed low
maintenance battery, I have tried opening my Vetus batteries and the tops
are sealed on by vibration heat sealing and therefore permanently sealed to
the base?
I am much inclined to agree with Ian Jenkins, Pen Azen when he says that he
now regards batteries as an item that has to be regularly replaced.
On this occasion I intend to research heat sensor probes fitted to the
terminals which I understand Xantrex and Mastervolt may have developed.
Kind regards,

Passageway metal plaque with lock missing - need dimensions

Alexandre Uster von Baar
 

The metal piece that goes over the passageway door, where you can add 2 locks, is missing. I would like to have another one made (unless I can find 1 for sale).
Could anyone please send me the dimensions of their?
Thanks in advance, sincerely, Alexandre
