Electrical problem resolved

[davidz71]

I think that with the help of forum members I have resolved my 110 v. electrical problem. I believe it started with a 30 amp plug which had loose blades and they somehow were arching inside the head of the plug. This was what was tripping the GFI system at the campground. One of the individuals helping me was an electrician parked in the next site. While diagnosing the problem, I believe he hooked a jumper wire from the ground bar to the neutral bar in the circuit breaker box, an acceptable practice for a nonGFI circuit according to several sources on the forum. No matter what we did after that, it would trip the GFI breaker at the campground box. Once I got home, a new plug was put on but I believe I checked it on a nonGFI circuit at the house because there was no problem when I tested it. When I checked it the other week, it was kicking the GFI at the garage breaker box. Since there was no reference in the service manual regarding the jumper wire, I removed it. That solved my problem. I have checked continuity on all wires and there is no crossing over. I have to isolate the ground bar to check it but it looks like everything is OK (I hope). Every plug and every system in the trailer has been checked with a meter and an instrument that verifies whether there is an open, fault, etc. and everything checks out. AC even checked out for a quick run of one minute.
Thanks for the help.
