Onan 3600lp turns propane regulator to red
My generator cut out last time I was out. That has never happened before. The 3600lp has always run flawlessly. I could start the generator up again but it would shut down after a few minutes. I n...

Its been a while but I want to get back on this and see if anyone can help. I have the Onan service manual and have been going down through the trouble shooting procedures for error code 36 which is what I am getting. I have tried two different propane tanks, two different propane tank regulators. I have verified the generator electronic shut off valve is functioning, but I bypassed it anyway and plumbed directly in to the propane demand regulator. I have verified spark and put in a new spark plug just to rule that out. I constructed a small manometer and set up the test to verify the demand regulator is opening. I have done a compression check and am getting right at 90 lbs.
The generator will start and run on carb cleaner but will not start on its own. I am stumped now. As far as I can tell the 3600lp does not have a low oil pressure sensor that might be bad. I believe the only function of the circuit board prior to start is to open the electronic propane shut off valve, so I'm not sure it could be the board.
Looking for any ideas. I have the unit out of the 5th wheel now so I can take it in to a shop if I need to, but I would sure like to figure it out on my own.
