Answer 2

Ouch...That will be a tough one.

You probably need an electronic technician that is good around tractors.

I am guessing it is a relay type regulator and a generator. Disassemble the generator and check the armature and brushes (possibly brushes on an old machine like that).

Voltage regulator contacts should be clean and not stuck.

Make sure you have good and clean connections on the wire ends.

Sorry I can't be more help, I was in my early teens when I messed with that kind of stuff and didn't know how it worked (Allis Chalmers, Massy Fergison, Farmall and John Deere).
