> For now I need some VERY basic answers - like what is the dashboard supposed to look like? I could really use a pic w/things marked. Most everything on this Major has been wired around - like separate ignition switch & start button - & the whole wiring is a MESS!
It's been a few decades since I was around a Major. As I recall, the original starter used a hand lever to activate the starter solenoid. The previous owner of your tractor probably couldn't get parts for the original setup and converted it to a standard starter relay. Which would require a starter switch that the original tractor didn't have.
I'm not familiar with the manuals available for Majors, but in my experience with Fords, the I&T manuals are a poor substitute for the factory shop manuals. eBay is a good source for original manuals and reprints.
