Onan genset removal question

Sorry....pics didnt work in original post.....

We can't see your images (they're sitting on your own computer, not online somewhere), but I think probably the wires you're talking about are the AC power output wires from the generator. There's a chance there's a junction box somewhere on the motorhome not too far from the generator where they could be unhooked.

I'd avoid cutting them randomly; to splice them safely and legally, you'd need to have the splice enclosed in an electrical box (per the NEC), and if it's exposed to the elements or road spray it should be a weathertight box with appropriate weathertight wiring.

On my Onan of that model, albeit quite a few years older, the neutral and ground connect to a little star shaped thingy inside the generator opposite the 12V ground wire connection (that, indeed, the 12V ground wire is bolted up to). The hot wire snakes across the bottom and connects to the AC circuit breaker. To get to them, it was necessary to remove the starter solenoid and control circuit modules from the left side and to at least partly disassemble the control panel unit on the right side. A torx screwdriver of the appropriate size was about the only tool required, but it did take a bit of labor and poking around in slightly tight corners.

These are the 3 wires that disappear inside the generator under a circuit board and I just cant get to them in order to disconnect them.

DrewE, I did exactly that. I followed the conduit that the 3 wires are in all the way to the back of the moho hoping there might be a disconnect someplace but wasn't able to find one.

Disconnect them at the junction box mounted to the interior of the genset compartment, not from the genset.

I removed mine a few months ago, KY spec, and you still have to do exactly what DrewE said. Solenoid, board, and part of the switch unit.

OK, I took a look at the solenoid & Circuit board. I can see how the solenoid comes out but the circuit board......not so much

Isn't there a small box mounted to the side of the genset compartment where the flex conduit ends?

I’ve seen the junction box a long ways from the genset, you could put another junction box closer if you like. When you find the junction box and pull the wires through pull a wire or string through the conduit for when you pull your genset wires back in.

There are screws, though they may be in dark corners. I don't recall any real difficulty in sussing out how to detach the components. On mine, at least, I think there were two circuit board modules, one on top of the other, and the top one had to be removed first before the bottom one could be extracted.

One hint: when you get to the point of actually lowering the generator, measure the clearance between the bottom of the skirt and the ground on the motorhome and check whether you'll need to drive that side up on ramps or something to get the generator out from underneath (which presumably will involve a dolly or floor jack or something underneath with wheels). The generator weighs something like 150-175 pounds.
