I am in the process of chasing all the connections up to where the battery shorted out. one of the cables goes to a 330a fusible link that isn't damaged, but another cable is connected to the same side of the fusible link as the battery terminal that winds it way along the rats nest of wires and cables. I hoping to locate where it terminates. Could the house battery Solenoid Switch be causing the drain? When I toggle the AUX battery boost it connects the RV and house batteries. thus giving enough volage to clear all the issues. If the issue is the house batteries draining, hitting that switch is like charging the house batteries with the alternator when I am driving. The part I don't understand is why those particular systems are on the house batteries.
