When my coach is on shore power, should the converter continue to power DC circuits when the house batteries are disconnected for service? My lights go out when I disconnected the ground on the house batteries to remove and service them. I was led to believe that the batteries were out of the circuit when the AUX Battery switch was OFF. We have an 06 Winnebago Journey with an inverter that charges the batteries. Any info would be much appreciated. John
