Greetings to everyone! I have a 95 Thor Motorhome. Always in the past all I had to do if I wanted to move from camping to driving down the road was simply unplug from campsight electric and start the generator. All of our electrical appliances / AC etc would work. Now if I am plugged in to camp sight electric everything works but when I unplug and start generator nothing relative to AC current works. No microwave or AC or anything except the 12 volt
battery operated lights and 12 volt
ceiling fans etc. The Onan generator runs excellent as always. By my circuit panel there is a switch that says: shore power / generator power. It looks like a simple electric switch found in houses to turn on the light bulbs etc. When I purchased the coach I was told the switching was automatic but perhaps something messed up.
Any help in leading me to what the problem could be is greatly appreciated!
