I have a 1989 Fleetwood Terry Taurus Model 33A. It never leaves the campground. Several weeks ago I had a leak in the roof which I repaired. Now all the lights from the bathroom forward do not work. The lights aft of the bathroom do work. I checked all the wiring, changed all the fixtures, changed the electrical breakers. Is it possible that there are to 12V inverters, one fore and one aft? I know there are two furnaces, so I was wondering. Is there any other possible reason why the lights fore are all not working?
