I recently replaced my 6K Onan powerdrawer after miraculously finding one
that ran on Craigslist. Using the local start and stop, the engine was
performing well and after some routine maintenance TLC, i fired it up using
the remote cabin start and she purred like a kitten, running both A/C units
like a dream for 30 minutes.
Just about the time my heart began to soar with everything right in my GMC
world, i decided to shut the Onan down using the interior remote and when i
did, the generator started to shut down but at the same time the starter
began trying to engage over and over again on its own with motor now trying
to run again in the meantime. Pushing the remote start or stop button
didn't help, so i ran outside, pulled open the drawer and was able to stop
the motor using the local stop.
The remote cabin start now no longer seems to work, and the local start
engaged the starter though the motor did not start again immediately. I
didn't want to push it to start and risk flywheel issues if i don't address
the problem first - whatever that problem may be.
i have a newer control panel that i rescued from the old gen set that i
could try. Seems strange however that the old control panel was working
perfectly and the remote start and stop was working fine only hours before.
any ideas would be appreciated!
thanks for your help.

I'm not sure if, by "control panel" you are referring to the control _board_ but if so it won't hurt to try the one from the old unit.
The problem you are describing is almost 100% likely to be caused by a control board problem.
The original boards are now 40 years old and over that time they have been exposed to two of the biggest enemies of electronics: moisture and heat.
Also: when a board fails they do so in bizarre ways. You've seen one failure mode. I have (had) one that would start cranking on its own, at random, with the vehicle sitting in the driveway and no one around. Others will start but refuse to run. Some refuse to stop.
If you have an original control board AND are worried about having a reliable Onan then I'd suggest you get on the phone to Jim K and order a Dinosaur board right away. I did and have not looked back.
