Old Norcold Fridge - Died Suddenly

There is no ground, or there is no positive. I never had to check. BUT, there will not be BOTH. You NEVER need Pos and Neg thru this type switch. You are only routing the wires together. That is why I stated, connect all at the same time and the Eyebrow may light up. IF NOT, then the rear board is bad. Doug

OK, well then something must be screwy because I definitely have a positive and I definitely have a ground in there. I tested the positive by running it to another known ground. With the red of my meter on the wire and the black on the known ground, it shows a positive 12v and a negative 12v if I reverse the leads on the meter.

Also... I discovered that I have a ground in there by accident, i.e. I put the known positive to a wire and got a spark, i.e. short circuit. Killed the 3A fuse. Fortunately I had bought more. This is the wire that I connected by bypassing the rocker switch.

So by jumping the known ground with another wire of the same color, I get 12v to the interior light.

Now... when you had said "light," I thought you meant interior light. Nothing I have done has yet given me eyebrow power nor power to the valve and ignitor.

Based on what you're telling me, it sounds as though my jump of the ground should have lit up the eyebrow. Do I have that right?

Also...

I have discovered that I have an issue with high DC voltage with the generator running. Makes me wonder if that wouldn't kill the board.

Even with all breakers off, i.e. the converter should be off, I get around 15.7v to the board. This at no more than 63 cycles and about 127v AC down to 58 cycles (heavy load) and 115v AC. Very perplexing.

On shore power, a flip of one breaker will kill the charging power to the batteries and kill the converter power to the house. 6300 series converter.
