Hello all! My family and I are new rv owners and have encountered an electrical problem that I was hoping someone could help with. We have a 1995 30 ft Prowler that was working fine the first few months. Our problem is the wall outlets and the 2 lights on the wall work but everything else does not. No refrig,heat , ac or outside lights(outside recepticles do work). We replaced fuses, had the camp ground check the hook up and nothing helped. We are hooked up to a 50 amp site. The camp ground suggested it may be our 12 volt converter. We have no clue what it is or what is going on. Any help would be greatly appreciated. Thanks
