There is several people who have replied that really knows the RV electrical. I am guessing by now this issue has been resolved. The one thing I noticed that no one mentioned that should be of benefit to a DIY is to know what wires connect to what terminals. Remember that oil used to be referred to as black gold. The black wire goes to the gold screw, the white wire goes to the silver screw, the green or bare wire goes to the green screw. On a standard polarized 15 / 20 amp receptile the gold screw will be on the small blade side. I believe Brett mentioned on a 50 amp RV plug / receptile, the two flat blades across from one another will be L1 & L2 and the red and black wires goes to them. The one flat blade below all by itself will be the neutral and the white goes to it, the round one is the ground and the green wires goes to it. Thanks to all who have shared and I hope this helps some one out there. Neal
