According to your schematic you need to have both the house battery switch and the engine battery switch in the closed position (i.e. on) in order for the shore charger to charge your starter battery. That is an interesting setup and I'm not sure quite why it's done that way.

Here's a quick description of your system:

The starter battery is charged via the "duo charger" which takes its current either from the shore charger or the alternator.

The shore charger will always charge your house bank even when all the battery switches are off.

The alternator will only charge when the battery switches are on (you should always have them on when you are running the engine). It will charge both the house bank and the starter.

The bow thruster and windlass will only operate when the house bank is switched on.

All this assumes that the wiring is as per the schematic and hasn't been modified.

I hope this helps.

Battery replacement

Thanks for the explanation Richard. I'm not very good at reading those diagrams.

No problem. Have you been leaving both battery switches on when connected to shore power? If not that could explain the starter battery not charging.

Actually I have. I think this start battery is toast. Won't take a charge.

There are two 30 amp fuses on either side of the duo charger. You should check those.

Is it not holding charge after a few hours of running the engine?

He indicated that he has AGM batteries.

I agree with everything Britannia said

If you want a more permanent 'Emergency' solution you might replace the Engine battery switch with a Perko 8603 Battery Selector switch.



Position 1 - the 'Normal' engine Start battery as with the original switch.
Position 2 - the 'Emergency' House battery bank only starting option.
Positon ALL - the Start and House battery banks are 'Combined' - can useful in some situations.
Position OFF - the engine Start battery is disconnected as with the original switch.

The wiring would be as follows:

Yes. AGM.

Ran for 4 hours and stopped for fuel. Dead.

Alternator is putting out 14.2 volts.

Ill check the terminals at the actual battery when I stop.

Can you check the voltage at the starter battery when the alternator is putting out 14.2 V? If it's low then there's a problem with the charging system. Yet another possibility is that the duo charger has died. You can check the voltage going into and out of that unit when the alternator or shore charger is running. If the output voltage is low then it could be dead. Check those two fuses too.

And I agree with Larry's suggestion

A combiner switch is useful. I installed one on my sailboat when I added a separate starter battery. On Stillwater the switches are set up so that I could use the house bank to start the engine or either of the generators

Larry and Richard are spot on. If you'd like help while you're probing around with a DVM, feel free to call my cell. nine one six 3 6 7 9 0 0 3.

Ok. Thanks everyone. I will check it out tonight.

Is there any huge problem with continuing to use the combiner to start it until I get it figured out?

Not that I can see. You just be starting from your house bank.

Just be careful not to run down your house bank if you're spending time on the hook. If you do then you won't be able to start your engine. That's the main purpose of having a separate starter battery.

Yeah. That's a concern. We are planning on being on the hook a few nights, but alternating between marinas.

I'm just pissed off at myself for cheap ing out and not installing the start battery when I was in there doing the house bank. Stupid !!

Run the genny. You'll like the nice cool air, and so will your wife. Yours should be quiet since its in a sound shield and in a separate room away from your master stateroom. We run ours all the time.
