After finding out the fridge in my coach was wired backwards and blew fuses and diodes every time it was hooked up, I was ready to correct the wiring problem but wasn't sure whether to swap the 12v feed wires at the fusebox or at the pigtail from the fridge.
Right now, in order to get the fridge running, I connected the pigtail from the control board at the fridge so that the black is positive and the red is negative ...not an ideal situation so I'd like to sort it out and correct the polarity so future owners won't have to go through what I had to. This fridge, even though about 10 years old, had NEVER worked. It is basically brand new and now works perfectly.
Question is: What wire coming to the fridge supposed to be + ? Is it the black or the white?
Is that the same system throughout the coach in the 12v system?
TIA
