I have an Onan 4.8kw gasoline generator in my RV, Model 5BGEFA26100N, SN H973723191.
It cranks and sounds like it's firing when I hold the crank button down, but when I release the button, the generator shuts down.
Last spring I took it to an Onan/Cummins shop and they got it working. They said "the brushes needed cleaning" or something like that.
We didn't use the RV last year, so the generator sat without being used for a year. Now it's doing the same thing, cranks and sounds like it firing when the start button is held down, but stops as soon as I release the start button.
Thanks for any suggestions!
