Are you sure you're in the right place? This forum is for Escape owners and perspective owners. As far as I know none of us have an Onan generator. Maybe you'll get lucky and someone knows something about them.

Check the connections on the solenoid , starter switch and battery.
Make sure they are all tight. Not our field of Expertise But always good advice when you’re getting just a click. If you think it’s the solenoid you might be able to jump it with a pair of pliers. Be careful and take your wedding ring off if you wear one. That’s all I got
