That oil leak has always been a problem. With units like that. Generac had a problem with theirs. I was surprised to see Onan do the same thing. Knowing the problems Generac had.
I don't talk to myself. This early in the morning. Why the hell should I talk to you.

Open up the generator breaker and see if it still overamps. If not, the problem is on the 'coach' side, if it still does, it's in the generator side.
I'm using the same battery cables as it was before it the breakers...I have them both turned off, are you saying disconnect the wiring from them altogether?

I know you have the same wiring as you had before, hence the quesions I posed.

Is the ground strap supplied by onan, that bonds the mounitng frame to the engine frame, in place, and tight? It had to be removed to replace the belt....

Is there a actual, thick, battery cable, from the ground terminal of the battery, running straight to the generator base itself?

You added rollers to service the set. If whoever built your rig tried to outsmart (or out dumb) onan and did not use a ground cable, You're now either trying to ground the set through the roller slides (bad) or through the AC ground wire (real bad), or both.

And it sometimes is obvious, but not always, did your battery go dead in the meantime? It happens......a lot.......

Your starting problems sound like not enough starting current. since computers hate the voltage being jacked around, I suggest we get that solved before we worry about why it's shutting down.
