Congrats on the great tractor.
I've been playing with old electrical systems for 40+ years. I usually make a working copy of the wiring diagram put it on my clip board and record all my readings as I go. I find that this usually helps with being sure to check all components and for later sitting back to figure out what to do. I ignore the color coding because I'm color blind and the color coding usually doesn't survive any repairs. You may save time and agrivation by replacing the switch right off. Then work from there. We used to rebuild regulators, generators, solenoids and starters. Drilled out rivets would be replaced with small bolts. Paint on insulation can repair alot of shorts.The old Motors and Chiltons manuals from the fifties and early sixties had detailed testing and repair proceedures for the componets.
I have found many parts that work in my tractors in the big surplus catalogs. Burdens and Baileys have been very good to me over the last thirty years.
Best of luck with the project. By the way I got a MagnaTrac GT
for my son when he was 5. I had to bolt 4x4 blocks to the pedals for him to reach. I then walked along side as he drove. He and his friends loved it. It lasted until he was 12 and got an old A/C B10. Tractors sure beat the mind dulling video games they want to play all of the time..
