I do not know how, but I lost all 12V in coach. I have 12v when the gen is running but if I turn off gen the 12V is off. I can not locate master switch - if any.
The battery switch, by the door, is going to solenoid. The solenoid work. I check the voltage with on and off. Somewhere I lost connection to control box. Are you suspecting that my charger may have something to do with?.
