Good day Sir, I was wondering if you could assist me. We bought a second hand 45 KVA Onan generator, same exact genset panel you posted. Problem is that the generator would start, but would shut off. It's not the voltage regulator or fuses, but when we checked the circuit board, we notice that number 8 has no supply thus it doesn't open the solenoid. But we also found that number 10 on the same circuit board traces back to ground on the body of the generator and that is what we are not sure about. On the video you posted, I saw 2 wires on number 10 circuit board. Could you please trace to where those 2 wires from number 10 on the circuit board go to? Just wanted to know if it goes to ground or not. I checked the manual 943-0019 Pdf and it doesn't give much. Thanks.
That appears to be a Stamford MX321 voltage regulator. It's probably aftermarket. Those jumpers select the frequency and stability options. Refer to 3w dot powersystems dot c o m dot au slash tech_pdfs slash MX321 dot pdf (Fucking TH-cam, can't post links. Assholes.)

Not too sure how to jumper it for 415 but I am sure its in the manuals for the machine!
should be a cool gen, over 100A at 415V is handy!
Much better video mate :) Raymond's pdf checks out, have look at the how the rectifier is hooked up

Dont know if this pdf is the right model mate, google search 943-0019.pdf
Look for this pdf 943-0019
