you need to verify that there is no output from gen set first.
I recently replaced brushes and a reluctor ring on a onan gen set . 93 model year.
1 there was a houshold style breaker in the gen set compartment.
2 problably no other (fuses) inline
3 could be transfer switch (switches from shore to gen or back)

start at gen set and work your way back.

Could be the transfer switch. I have had two of these go out. I hope for your sake it is just a breaker.

This diagram should be typical of most Onan Generators. The Breakers are generally on the left side near the top. to the forums.

As far as I know, (from older onan generators), if it starts and runs it is making power, just not making it to the panel. The famous "Onan will stay running as long as I hold the start switch down" is generally because the genny isn't producing power or a safety switch is open. If the genny starts and stays running its making power and safety switches are closed.

The reason they do this is when the start switch is held down it is bypassing the safeties in the genny so that it will start even if oil and such has low pressure(which it will till it starts), but if there is an issue with one of the safeties or its not making power it will shut down when start button is released. This is the short explanation.

So the fact that yours starts and runs just fine I would feel pretty confident in saying its a bad connection in wiring or the automatic transfer switch is bad, this is a common problem.
