Batteries dead while connected to shore power
our 2018 Thor Windsport is connected to shore power and something is draining my batteries dead, (both, vehicle battery and house batteries). The TV and refrigerator didn't work, of course. I charged up the battery bank for 24 hours and all was well.
Until 3 days later, the batteries died again, while on shore power. I checked fuses and circuit breakers, converter. Inverter wall panel shows over 13 volts.
Any ideas appreciated....
