Nope. The little 80amp alternator puts very little back into the house bank, even after motoring all day. Genset or shore power is your primary source of power to recharge the house bank.I'm needing to charge my house batteries with the generator after motoring all day.

I've chartered similar boats with no generator and the charter company recommends running the drive engine a couple of hours a day charge the house batteries go figure that always workedNope.

Thanks Bob I will be checking out the electrical system I think the previous owner made some modificationsI encountered a similar problem a few years ago where the engine alternator was charging the start battery but not the house banks. Turned out to be a bad solenoid in the charging circuit, about a $35 replacement on Amazon.
Well not so quick. It depends on the state of both the Start and House Batteries.Nope. The little 80amp alternator puts very little back into the house bank

The alternators on our boats are sensitive to heat of the engine space. It is normal for an alternator rated as 80 amps to be putting out 50% or less of its rated capacity.The little 80amp alternator puts very little back into the house bank,
Absolutely correct.I've chartered similar boats with no generator and the charter company recommends running the drive engine a couple of hours a day charge the house batteries go figure that always worked
This is because Hunter used solenoids that were not desgned for the duty. Later on they upgrade to Blue Sea Systems ACR's..I encountered a similar problem a few years ago where the engine alternator was charging the start battery but not the house banks.

Jim,Well not so quick. It depends on the state of both the Start and House Batteries.
Look for this device on your boat. Mine is 1997 inside the Engine compartment.

This is what charges the House Batteries, when the switch on you engine activates the Grey Solenoid.
You can check to see if all the Red Wired connection are good ≈ 14.1 VDC, and if you have a clamp on DC amp meter verify the charge.
Once your Engine Alternator tops the Start battery, you should have 70 amp available to charge the House batteries.
All Checks must be done with your Engine Running, even at idle speeds. It should take some time to top off the Start Battery.
This device is sometimes called an ACR.
Jim...
PS: There are many things depending on all in working order. Include your ignition switch.
And the Grey thing is the Solenoid/Relay.An isolator is a diode based electrical check valve. An ACR is a relay.
