Some time ago we had an electrical fire, caused by the passenger window visor motor getting stuck in the down position and apparently short circuiting. The company did right and replaced both drivers and pax shades but since then we have had no power to the pax shade and the driver and pax seats. In studying the wiring diagram it appears that both the seats are hooked up to a 30 Amp CB47 (circuit breaker 47?). The only 30 AMP breaker in the system I could find was under the Inverter in a junction box, photo attached. It is made by Deltrol Controls and is a complicated piece of work, apparently handling 15/30 amps and 300/600 volts. In the attached photo I can see a black spot on the left of the bottom breaker, and though difficult to see, it looks charred and different from the other two; not just a piece of flash, but bubbled a bit. 30 amps is certainly enough to fry something. There is no trace of power at the power seat lead on the terminal board in the electrical bay. Am I looking in the right spot? I can't find any continuity between the pax side visor switch and the shade leads and certainly no trace of 12volt power; these are 12 volt, right? The driver’s side works fine before and after the event and I can only assume it is on a different circuit. I can only assume that the pax shade was getting power from the seat circuit. I would appreciate any tips, I'm taking the coach out to have a slide issue addressed, we have no slides either and it looks like a hydraulic leak is the culprit, but I would like to address the seat issue on my own.
