Electrical diagram for 2001 WH P32 power supply feeding Onan genny

[ROAquaman]

Hello fellow travelers,
I am working on chasing out loss of 12V power that feeds my Onan generator. I have 0 V at the 12v power terminal on genny main feed. Anyone have an electrical diagram showing power feed to generator.

This is an Onan Tiffin thing. If you are getting 0 V on the large cable on the cylinoid you may have dead house batteries or the BCC is in disconnect. If you are getting 0 V on the positive terminal on the cylinoid that can be many things. If house batteries are OK try to jump power from the main cable to the positive terminal on th cylinoid and see if it spins. If it does It could be a bad switch in that system. Need to find it in case lt is a safety issue before you just straight wire with a new start switch.

I’m still not sure why I had no power at genny power lead but found the new replacement Solenoid was bad. Replaced and now she purrs like a kitten.

Thanks All!
