The generator will run as long as you hold the start button down. It runs smooth but produces no power while you hold down the button. It must be one of the limits that shuts it down. The only thing I can reach while it is in the rig is the control card. That I have replaced and it did not fix the problem. Now to reach other parts I will have to remove it from the RV. The voltage control is on top of the generator and I cannot see it. It looks simple to just drop the generator out of the rig so I can see the hole generator. I cannot even remove the tin work to see what is under it. I also would like to put a oil pressure gauge at the same time so I can see what the oil pressure it. The generator only 303 hours of run time on it. I wonder who long the brushes should last. It has been setting sense 2006, they maybe just stuck or dirty.
