Re: Onan does not start

Check the DC circuit breaker above the red emergency switch. If i remember correctly, yours looks to be in the off position. I may be wrong and I’m not on the boat to check, but it happened to me twice to inadvertently knock it off while in the ER.

Hi Paul,
   I instinctively say it is the DC circuit breaker, the red switch on the Generator panel in the ER.  I see it looks to be on, try cycling it.  My switch can be bumped when doing work in the ER and look like it is still on.  

I am not 100% sure about the solenoid that connects the DC negative, if that also connects the generator control power to the neg terminal.  If so that could be the issue as that scenario the solenoid would first close then allow everything else to fire up.   I'll be back on the boat this afternoon and can double check.

My Onan is totally dead nothing happened when trying to star not a slightest click. I have measured 12,8 volt between +on the starter and minus on the alternator, but only about 4 volt between + on the starter an - I believe it is on the starter see attached photo the same reading 4 v between plus on the starter and the ground strap.
I assume the reading should be 12,8 and not 4 volt?
Any idea where to start searching?
