OK, got the coach home today and checked the wiring in the shore power cabinet.
I was just looking to see if anything looked like it shook loose or something. While checking I saw a faded strip of paper attached under a set of wires going to a number of little black boxes each about a inch long and 1/2 inch wide. The strip of paper said reset button for house and fridge on top or bottom. It was actually on the left side and when I pushed it in the lights and fridge now work. It seems the problem is solved.
I think I just got dumb lucky because I know very little about electricity and testing stuff. Thanks very much for all of those who were trying to help. I am wondering if the dead house battery may have tripped the reset switch somehow.
