When I said wall plug I meant where the electric cord from the hookup plugs into the motorhome! Sorry about the confusion. Anyway, they looked at the transfer switch under the bed ( A pita to get to)and found that it had power to only one side. The unhooked the switch and tried just 120 from the cord but that didn't work either. They tested the cord and it was okay, so they looked at wiring at the plug in out side the wall of the MH - sure enough ,a wire had not been tightened down- tightened it and everything including the generator works! They also found two wires for 12 v that went to the fuzes that had no wire nut, and fixed that. I guess the electrical installer was in a hurry when he did my MH . One of those intermittent things that are hard to figure.
