Before you get to far down the Pike troubling your Onan, disconnect the
wires going to the Onan's Voltage Regulator (left rear on top) and tape
them up. Now try starting Onan. Your symptom sound like a low AC voltage
at the Control Board (should be 26 - 30 V AC from terminal 8 to 11).
Also, bad cable connections will cause the same symptom. While trouble
shooting, temporarily remove the 4 wires at top of board & at terminal
12. The Control Board should function w/o these wires, which could be
your problem.
