Onan generator switch?

Good luck! I hope you finally found the issue. I recently went through similar teouble shooting with my Gennie. I also have a Majestic (former CA rental) and had to replace the 30amp breaker on the Gennie recently because it rattled loose and broke. Hope you solved the mystery.

Well I guess this has turned into a diary for people who have the same problem!

I took out the module and looked for any loose wires. Everything looked fine. Finally after looking several other places I determined that I needed to check continuity between the wiring harness and the switch. Turns out that there is no continuity in the yellow/red wire. Looks like I found my issue. Now comes the hard part....finding where the wire is disconnected. Let the fun begin!

Assuming it's similar to mine (which may or may not be the case, as I'm not in a position to check the model number), there's a small (5A?) DC fuse on the little control panel on the generator itself, next to the start/stop switch and the AC circuit breaker.

The main DC power feed to the generator is of course a much heavier wire, and wired more or less directly to the battery of the coach (in my case, the chassis battery, though the house battery is also used sometimes). This connects to the solenoid for the starter, and thence to the starter, with a wire for the control power for the generator also attached to the input side of the solenoid.

If you don't have 12V power getting to the starter solenoid, you obviously won't be able to start the generator. That may be switched by a battery disconnect switch somewhere or some similar arrangement.

Yes that is what I thought too. The pictures in the manual show it should be there but there is no fuse. No housing for one either. I took the casing off and looked behind the switch and no fuse. There is no fuse in the main fuse panel either. I have no idea where it is. This is a RVQG 4000 genset that is the K Spec series. The manual listed a few posts back is for spec series up to G.

On my MH there are several circuit breakers located in a compartment. They look similar to this one at AMAZON..

Pulled the 3 wires and they are for the 120 off the gen. Those wires needed to be redone anyway but they don't have anything to do with my problem. I still can not find the fuse. Does anyone know where the fuse is off the gen to starting???

The model number is rv qg 4000. I have still not figured this out. I cut and spliced the 6 small wires that go into the generator and connect to the remote start. There are 3 bigger wires that come out down there. Does anyone know if they have anything to do with the remote start? I have redone the ground and am about to start pull everything out and apart.

Here is service manual link that should be for your unit.

I think it is an onan micro quiet 4000 but I will have to double check that tomorrow in the light. Thanks for the help Bud

What is the model of the genset?
