Onan Marquis Gold 5500 problem

#1
I just bought a 2002 Fleetwood and the generator will not stay running. I have remove carb. disassemble and clean, complete service oil/fuel filter. The fuel tank is 1/2 full. When the starter is turning over it will run smooth but when I release the start button the fuel and the ignition shuts off. I am thinking it is a electronic relay or something but trying to see if any one has answers or a common problem. Model is 5.5 HGJAB-901A Thanks

Could be a couple of problems. The board could be bad, the regulator could be bad, the brushes or rings could be dirty, or if equipped with a low oil switch oil could be low or switch could be bad. I am assuming it has 150 hours or less on the gen set. If it has a lot of hours the brushes could be bad.

Had same exact problem as you describe on my 2002 Fleetwood. They had to replace control board.
