Trying to help out a fellow RVer. Has a 2004 ish HR Ambassador , no 12V at all, lights, furnace, water heater nada. I have an 07 but they are very different. Checked pedestal, inverter, turned both of...
Time to get the volt meter out and start back tracking. There may be a couple of circuit breakers on the inverter. Make shure you have a good power/connection around the "Salesman switch". I don't know if the "Salesman switch" is the main switch or just operates a solenoid. Bill
