MF383 starter wiring?

[TheEquineFencer]

G/F's MF 383 won't crank. I thought maybe the battery was dead, it's charged. I've washed the "dirt and mud" from the dash. The Ignition switch appears to be a 4 pole switch, turn it to crank and it looks like it's sending voltage out. At least it goes into the harness. I then started checking from the starter back. The wire goes from the starter solenoid, back to the neutral safety switch, I have continuity to and through the switch. I cannot open the hood because of the FEL. I know the PTO has a part in the crank circuit too. Is there a relay somewhere that's also for the start circuit that the PTO switch is wired through? I'd love to have starter wiring diagram. The FEL is a PITA to take off to just open the hood. I'm almost ready to rewire the thing if/when I can get to the PTO switch so it can't be cranked unless it's in "N" and the PTO is disengaged.
I'm swamped with "broke farm equipment" right now....SMH...
