Customer Question

I have a 5500 onan generator in my toyhauler. i recently wasrunning a harbor freight water pump while boondocking off of my 2 batteries to refill my holding tanks. My generator was running perfectly before I did this but off while I was pumping the water. When I finished pumping water I went to crank the generator and it cranks and starts while holding the start button but dies the instant I let off the start switch. I just bought a new circuit board, came today, put it on and its doing the same thing 400.00 bucks down the drain!! Help!!
JA: Do you have fuel in the tank? If so, is the shut-off valve open and the fuel clean?
Customer: It is full, the pump is running it will run as long as I hold the start button down
JA: What happened just before this problem started? What troubleshooting have you tried?
Customer: I just explained it, no trouble shooting, read the forums and talked to an onan mechanic who said by me running the pump without the generator running I blew the circuit board.
JA: Anything else you want the engine expert to know before I connect you?
Customer: I tried the oil pressure switch ground, didn't work
