If you are starting it from inside the coach, I would suspect the rocker
start/stop switch contacts or the multi-pin connector behind-underneath the
ONAN. If you are starting it from the control board on the ONAN, I would
inspect the rocker switch on the board, the starter solenoid, the bendix
drive on the starter. Think "things that move". They are subject to dirt,
corrosion, wear.
