The tractor in question is a 1965 541 with a negative ground system. It has a Prestolite generator, which I just had overhauled. The repair shop also sold me a new regulator (at my request) and said they polarized it.
I got the tractor running today for the first time, and the GEN light remains lit at all throttle settings. The tractor does not have a load meter or ammeter.
How should I proceed troubleshooting this one? I am fine with all things mechanical, but must admit, electrical systems and electrical issues are “Greek” to me. Any guidance or suggestions would be greatly appreciated. – Joe
