Sorry don't know the number. Mine has lived indoors plus has a cab keeping it dry. I would think NAPA could get you a switch if you describe the positions. Search function on this site is poor.

Jumpered solenoid. Started.

if it started when you jumped it to the solenoid, you have some bad battery cables and/or you battery has a bad cell.

Mine didn't start when jumped. cleaned cables still nothing. Battery is good in tractor and I jumped from my F-250 while running. Pulled starter and it bench tested fine. Not sure what else to try.

If yours is the same as my friends, for testing sake pull PTO lever all the way back and then push forward till slight click is felt. put both selectors in neutral, push in clutch pedal, turn key to run. Should hear a click and louder clack. Then turn to start. Other than that, idk other than to run everything down for voltage drops. When you turn key backwards from off position does it turn on glow plugs?
