RV QG 4000 Onan Generator Not Starting From Remote Panel

Hi all,
I'm perplexed with my problem and not sure how to troubleshoot any further. This generator is in a Coachman 27 foot class C coach, and the remote switch no longer starts the generator, although the remote switch does stop the generator.

I verified the remote switch is operational by using a DVM, and switching the leads to have the start work when you push the switch down instead of up.

I verified the 3 remote switch wires make it inside the generator wiring harness junction.

The generator starts and runs great when started from the generator itself.

I think this is telling me it's either the control board or the solenoid, but I don't know how to troubleshoot either.

If it is the control board, then how do I remove it?

I'm assuming the solenoid hot lead is coming from the coach batteries, and I think it would be easier to disconnect from there instead of working at the solenoid.

Greatly appreciate the help.
  • I had the same issue and mine was a rubbed through wire that i could not get to. I did a continuity test on all wires and found one not reading. I ran a new wire from the gen to the front switch. Issue solved. Like i said before if there was personal pride in the workmanship of all rv's this would not happened.
