Default I'm looking for a wiring diagram and advice on an Onan DJA-3CR/3005U

Hello knowers of all things Onan, I live off the grid in Oregon and just picked up a single phase 120/240 vac 3kw Onan genset serial number A780297029. My Genercrap 12k Guardian finally put me out of my misery by seizing up, and I want to hook up the small Onan as my backup until I can afford a new more full sized model with leather seats. I know a 3kw isn't much of a replacement for the 12kw that just died, but that thing rarely put out more than 3kw anyway. My problem now is that I'nm not getting 220v across any of the leads coming from the generator, so I hooked it up 110v and under load the frequency drops to 52hz. If any one can push me in the direction of a proper wiring diagram for this model and some advice it would be much appreciated.

Recieved thank you. Problems persist though, this morning when I started this thread the generator was running and I attempted to adjust the governor while under load, I let it run for a few minutes and went inside to disconnect the load and see how the generator reacted. Once there was no load the Gen rpm increased and by the time I got back outside to check the readings the gen shut itself off and now it won't start. It decompresses as soon as I let off the starter switch.

Look at the wiring diagrams that I sent you.... follow the voltage to the Decompression solenoid to the Battery. somewhere you have a disconnect....
