Plugging into the shore power doesn't really seem to charge the battery? The battery was brand new last year. My question is on charging. The voltages below were measured under different conditions. The one constant was my Maxxair 4 speed vent fan was on high. The only conditions that charged the battery was the motorhome running or an external battery charger connected? The generator and shore power didn't raise the coach battery voltage above 12 volts? Only a large battery charger or the coach running seem to charge the battery? I can never get through a night on battery power? The battery lasts a few hours then dies. All lights off and refrigerator on automatic the coach is dead before morning?
