VERY strange electrical issue..
Greetings, I'm hoping one of the tech geniuses on this forum can help with a problem that has me absolutely stumped. A brief history..
2008 Pilgrim RKS25 with a 55 amp WFCO converter (don't have the model number w/me at the moment but can get it if it will help someone troubleshoot. )
On our last trip out, as we were just about to move on and were already unplugged, I suddenly had no 12 volt power. I decided to figure it out at the next stop, so plugged in my 120v to bring in the slide and off we went.
At the next stop, I found the 12v working again, with no apparent reason for the problem. We plugged in at the campground and all seemed fine, until about 3am, when the main 120v circuit breaker blew. There was nothing on except the converter and a fan. I reset the switch, and everything was fine again.
That evening I went to plug in in my driveway, and had no 120v, the 12v was fine. I checked the panel with a multimeter, and had 120v at the panel. (More on this later)
Last night I took out the reverse polarity fuses, (even though that would cause the reverse problem I believe) and they were fine. When I put them back in, I got a little spark - and then had no 12 volt! Fuses are good!
Checked battery and read .245v. Hooked up battery charger and received an error that said incorrect battery connection. (Charger was correct and battery hookup to TT never changed.) disconnected battery from TT and hooked up charger again. Read 2.5 v, but then received 'internal battery problem' error. Last night I had 12v lights in camper, so something went wrong with the battery since then. I am thoroughly confused!
Back to the panel..
With my multimeter, with the black probe on the ground bus, and the red probe on the terminal screw of the main circuit breaker, I read 126v. Same deal with the red probe on the neutral bus and black on the ground bus.
Also with the black probe on the ground bus and red probe on the terminal screw of any other circuits I get 126v. Strangely, this is the same no matter the position of the main circuit breaker. It would seem that the main breaker is bad and giving the circuits power at all times, yet none of the outlets work! I have checked the only GFCI in the TT, but it seems I can't test/reset it because it has no power! Am I losing my mind?!
Is there supposed to be power on the neutral bus?
Does the shore power come into the terminal screw of the circuit breaker, then is connected or disconnected from the common bar behind the breakers by the switch? If so, I must have a bad main breaker, but that doesn't seem to explain any of the rest of it. It seems I may just need to dump the converter and start over.
Any help or suggestions would be greatly appreciated!
