This weekend the interior lights quit working while hooked up to the 12v coach battery on my 1988 Coachmen pull behind. I am electronically challenged!! So far this is as far as my troubleshooting has landed me... The water pump works still, the lights DO WORK when ran off of 110v(the generator). None of the fuses are blown. Is there a "master" rocker switch that controls all the lights in the camper while connected to the coach battery that accidentally got flipped? I know there is a switch in the bathroom that will turn the lights on and off in the bathroom only, but is there a switch that controls the whole camper? My camper is 125 miles from me now, we primarily use it to hunt out of, we DO NOT run the generator from 10pm-11am (getting dressed in the dark this morning was tough). The converter box is still working apparently.. is there a relay in the converter box that just operates the lights? ANY help would be appreciated.... where it is we are 100miles from an RV center and I dont want to loose a whole weekend in the woods to just "get the lights working".
