tripping air conditioner gfi

[fernjohntexas]

replaced air conditioner on 2510 hi lo, blows gfi outlet in bath. have power wires to ac unhooked and capped off and still trips gfi when i turn breaker on. no continuity between white an black wire, continuity between white and green wire. any ideas? checked gfi outlet by plugging something else into it, doesn't trip

Should there be continuity between the white and green wires? In my trailer, white is ALWAYS ground wiring. The green wires are DC power supply wires (as I recall, for the running lights).

Green is the earth ground for the romex on the 120 volt for the ac. I found the problem, There was a connection where the wire comes out of the roof that had extension wire for the ac . It is a plastic connector that loosened over time. Took it totally out and hard wired the extension and all is working fine now. The gfi was sensing voltage loss between hot and neutral wire.

OK, that makes sense. I don't think any of the wiring diagrams show the wiring to the A/C, and I've never had to service mine.
