I have had several issues on different Onans where the starter wanted to
continue to run after start up from the remote switch. I just ran into an
onan that has not be used recently, where the starter would turn but not
engage several times, then engage and start from the gen set. Then it would
die when grounded but when you release the rocker, it would start up again.
It took Several actions on the rocker start switch before it would quit its
start function.
I had been told previously that the malfunction was in the board. This seems
to me that it is in the rocker switch on the gennie itself.
Also, I believe the attempts (turn) but not engage is a malfunction of the
starter (dirty bendix?) and not related to the malfunction of the rocker
switch.
Please chime in here and give me your thoughts.

The main and remote switches are paralleled. I’m guessing you have green corrosion on the Molex in the remote cable behind the generator. If you mark the top row of wires on the gen board and pull the Faston connectors off, you can positively determine if the board is behaving OK or the remote is the problem. If switch on Onan behaves normally, problem is in remote wiring. Inspect and clean Molex or cut, solder and shrink for permanent repair
The first starter symptom you mention sounds like a separate starter drive needing light lubrication issue.
