My question is: I have 4 each 6 volt batts as house batts. I have 2 each 12 volt batts for starter. My coach has a converter charger (no inverter, yet). My alternator charges only the starter batts. My house Batts are charged either by on board genset or shoreline hookup. The house are the starter batt for the genset. If I run house batts down I can't crank genset to recharge them. Does this sound like a lodgical set up? I bought the coach used and wonder how it should have come from the manuf. Any anyone knows and has any suggestions on how I should set it up.
Thanks
