So I connected the open end to a convenient spot on the coach's chassis framing that supports the generator. That cable isn't necessary at all since the generator and coach chassis are tied together at multiple points. Obviously Thor forgot to connect it during assembly.

But I am still waiting to hear back from Thor about the dash cigarette lighter sockets being dead.

the onan ground is required for proper function of said genny. Yes it more than likely has several shared grounds, some may be smaller gauge wire and may not like the heavy current draw to start the genny, then it may not ever become an issue.


my power management is sensitive to grounds and will trip out. its also very sensitive to the returns as well on the 120 volt side.


good you figured it out .
