Switching from 6 to 12 Volt
If the tractor is a positive ground system it will have to be switched to a negative ground polarity.
To do this reverse the battery cables, reverse the amp gauge wires (negative ground = negative terminal on the coil going to the distributor)
If equipped with lights change the bulbs to 12 volt. You might consider a 0-60 amp gauge as most generator gauges stop at 30 amp.
Attach 1-wire from the threaded stud on the
rear of the alternator and run it to the amp gauge, run a separate wire from the other amp gauge terminal to the positive side of the battery. When initially starting the tractor rev the engine to approximately 850 rpm to excite the internal regulator, the system should start charging.

What I’ve done on a couple of mine is to have the generator rebuilt to a 12V and used a 12V regulator so the restoration looks right but I still have 12V . They also put a stronger spring in the starter so the starter doesn’t engage too fast or hard. On my older ones I don’t really need the extra charge rate of the alternator.
how much did it cost you to convert the generator?
What is involved in converting a 6V generator to 12V? Who does this type of work?
Tom here is a link to some of our 6 to 12 volt conversion videos. Good luck on your project. 🙂
