Onan No Start


New Member
I'm having an issue with my 7.5 Onan Diesel generator. I have checked all connectins but I am not getting voltage to the starter soelnoid. I have ordered the service manual but that is 7-10 days away. Anybody have an idea what the problem is or a direction to look for the wiring diagram?

Re: Onan No Start

It sounds like you either have a bad battery, or a battery isolator problem. If you have a meter, trace the voltage from the battery to see where it is lost.
