Onan Emerald 4000

[Mrblueeyes2020]

I have a 91 Winnie Warrior on a E350 frame.

My generator ran fine last year , went to start it this year and gave me issues at first , now when I press the generator start button after priming there is only one click. It doesn't try to turn over.

Help me figure this out please , batteries are new. Tried direct jumping with cables and same thing.

I would start with the basics - clean all the battery grounds as well as the generator ground - clean/tighten the battery connectors - and make sure the batteries are fully charged. After that - start your engine which will put your chassis and house batteries into parallel mode and then try and start your generator using the start button on the generator.

Did you jump to the battery or directly to the gen?

Sounds like it's probably either a bad starter solenoid, a loose or bad wire between the starter and the solenoid, a bad starter, or a bad ground probably in that area. (That is assuming the engine isn't physically seized and can be turned over manually.)
