C-750 Runabout Electrical Question

I am not an electrician, but have done lots of residential wiring. I do not think that wire is used. As I recall, years ago the wire was connected to the gas pipe. I think it is no longer done that way. My TC is a 1988, and it does not use that ground wire. It does use the three wires from the extension cord, as does yours. Black is hot as yours is now wired. It connects to the service bar that feeds your breakers. White is neutral and connects to the other white wires at the terminal block. The ground (copper non-insulated) connects to a block with all other copper wires. The copper wire hanging outside is no longer used. to be of any value, it would have to be connected to a ground rod eight feet long, driven in the ground, or equal. Personally, I would disconnect it from the propane line. That is probably why it was cut off.

I think you are wired correctly now. Do you still trip the breaker? Do you know if the receptacles in the TC have the correct polarity?
