Voltage regulator

Thanks Kevin,

I appreciate your answers. I think the Balmar VR setup is the bomb!

We then discovered if the house battery is off the bus no start. Don't know why BB designed it that way, must be a reason. I guess I could switch the sense to the house battery, but it would still be combined when the Ignition is on.

I have no idea why BB did that and haven't heard of it before. Maybe a WB owner will chime in.

I only bring up the idea of having the alternator high amperage output on one bank and the sense wire on a different bank because failure of interconnecting constant use solenoids could mean trouble; some birds are wired this way. I think it's best the way you have it.

Yes I can. I have a 24V 270A 50DN charging the house and a 24V 140A Bosch alternator charging the chassis, but they are switchable in case one fails; i.e., the 50DN can charge the chassis and the Bosch can charge the house battery banks.
