A big THANK YOU to everyone who gave me
advise and sent instructions on
troubleshooting and repairs of this system.

again.

I'm curious if you are an electrician, electronics technician or electrical engineer?

Thanks for responding to tell of your success. Always a good feeling

So what was the problem or problems?

I'm not an electrician, I'm a mechanic, heavy equipment operator and truck driver at my work. I do know about repairing 6, 12 and 24 volt systems but this 12/24 volt was a different challenge, but a good learning experience. I found several wires that weren't hooked up or hooked up wrong and the resistor in the ignition switch had too much resistance, but the main problem was a small wire that connects two terminals on the starter was missing. I wouldn't have known that without the wiring schematic of this unique system that a few guys had sent me of the factory service bulletin for this tractor.
