Hello, my name is ***** ***** I am going to assist you with this.
While the genset is tunning, does it run smoothly, or is it surging?
How long does it run before it shurs down?
When it shuts down, does it just shut off like someone turned it off, or does it start surging before shutting down?
When it shuts down, does it start right back up, does it only restart eith extended cranking, or does it have to sit for a while before it will restart?
If the valves are good, do a compression test and make sure you don't have a bad ringThe controller is shutting it down - that's why a code is being set.
Code 36 means that the controller does not know why the unit shut down. It is most often a fuel issue, but can also be an engine issue.
Since you are certain it is not a fuel issue, start eith the valves. Make sure both are gapped to .002". Onan had an issue with bad valves about the time your unit was built. Rocker arms ha a habit of cracking.
If the valves ate good, do a compression test to see if you have a bad ring.
Let me know what you find.
If something was telling the controller to shut the unit down, it would be setting an appropriate code.
Code 36 means that the unit shut down, but thecontroller doesnt know why. It is either fuel supply, or engine mechanical, or a bad controller.
The controller would know if someone hit the stop switch, low or high voltage, low or high engine speed, or a faulty field.
It does sound like that, and a bad coil or magneto will do that, but normally when a coil or magneto goes bad, it will run for 10 - 20 minutes before it shuts down, and then must sit for a half hour or an hour before it will restart.
The fact that it is only running for a minute, and will start back up in less than a minute does not indicate a col or magneto breakdown. That is not even running long enough for them to heat up.
A bad controller might do that, but with the cost of a controller, I would not advise you to just get a new one. It would be best to have the genset fully tested by an authorized Onan dealer that has a Break Out tool. It is a tool that can be plugged in place of the controller, and will allow the engine to stay running while the entire genset is tested. If every other subsystem tests good, then the controller is replaced.
Not a problem.
If you have trouble finding an authorized shop, let me know.

Actually, I can believe it. I have seen some strange things in the 15 years I have been a generator technician.
Obviously, I have no way of knowing something like that. That is the type of thing that needs to be physically seen.
I am glad that it was something so simple.
