Getting back to my original topic, I now have my motorhome in the shop for loss of back up camera, turn signals, stop lights, dash lights, windshield wipers, and other electrical maladies. Because it occurred after being out in a torrential storm, my inclination was that it was related to this. It is still in the shop, but the initial diagnosis is that I need a new ignition lock and possibly a cam that goes with it. It seems my lock does not return to the same correct place after it is in the starter crank position and that different sets of contacts are being made with different functions being disabled. Compared to other possibilities, it will probably be a relatively simple fix. Just thought you all might be interested in this if you ever have similar troubles. Mine may be aggravated by the fact that my 6 year old unit was driven only 4K miles by the first owner in the first 4 years and the mechanism may have gotten gummed up from lack of use.
