I recently returned from a problem free trip. I let the coach sit for a couple days before I realized that I still had some beer in the fridge. I went to plug it in so that I could cool it down and right when I plugged the cord into my outside outlet I heard the GFCI pop. At that exact same time I saw a very plump mouse fall down from the underside of the coach about mid length and flop on the ground and then run away! SOB!! I figured the little prick was chewing on a power line and was zapped when I plugged it in.
With that in mind I started to try and find the ground fault. I looked under the coach at the same location and couldn't find anything that he could be chewing on. I went inside, killed all the breakers and tried them one by one to find the short. I would trip the GFCI no matter which one was powered once I put load on the circut. Later that night it dawned on me that the short was a neutral to ground rather than power to ground short.
Tonight I was able to isolate the short to the line powering the fridge on the other side of the coach. After hours of trying to find the line the mouse was chewing on it probably was an innocent bystander that was zapped when I plugged it in before the GFCI blew.
Everything runs fine now but I had to disconnect the ground lead from that circuit to get it to work. I play to trace the line back to the power box to either find the fault or open a path to pull a new line.
All of the AC power in my rig was replaced by the previous owner so the quality is suspect.
