Random Breaker/GFI/Surge popping

[Edw]

Hi All, Have had my 1999 National Seabreeze for 2 years with no electrical issues. This May it started blowing the portable surge protector while plugged in at home. Also when resetting the surge it may blow the 20 amp house breaker. Everything is unplugged and I isolated it to GP1 on the coach panel. When turning on this breaker it may trip something. I disconnected the wiring at the Kitchen GFI (this may be first stop from panel) and when turning on breaker all is fine. What would be best way to isolate problem/short. Some of the GP1 cicuit is direct to outlets and some may run thru EMS. I have 117v on direct and 115 on plugs after EMS. DO I need to disconnect all wires on GP1 and test for shorts? And finally - does anyone know/have diagram of this circuit layout? or what is wired from what?
Thanks, Ed

Ed, I'd disconnect the GFI and tape it up then turn on the power. Test all the plugs. Rule out all the plugs with power. Turn power OFF. Reconnect the GFI. Proceed to the next plug in the circuit and disconnect it. Turn the power ON. Does the circuit hold? If yes move on. If no replace the receptacle, try again. Just keep working this method until you found the bad plug or have isolated where the short or fault maybe in between one plug and the next.
