Using a Chrysler Alternator To Convert Tractor To 12V?

Has anybody ever converted a 6v tractor electrical system to a 12v system by using a Chrysler alternator? :shruggy:

You got to redo the wiring anyway. Keep it 6 volt. Save on headaches and problems with igntion and lightbulbs and or gauges. In the end you will have an original tractor thats redone. Theres nothing wrong with a 6 volt system.

I have been considering that. My gay lover bought the tractor ten years ago, to cultivate tobacco. When he bought it, the gauges were fried, (Something else to replace :eyes:), and the lights had been removed and sold. The wiring still worked at that time, but it is done now. (The tractor is done too. No Starto) The problem with keeping it 6V is finding sealed beam headlights. The tractor isnt a showdog, and will still be used around the farm. (Fast-Hitchs are very useful, despite their forgottenness.)  So the lights are a must. Hmmm...I really dont know.


You can find sealed beam 6 volt headlights and lights all over the place.

I converted my Farmall H over to 12 volt.I kept the 6v starter.everything else is 12v works great.but i did use the chevy alt. :brickwall:
It was free and had it laying around from a motor home.oh well good luck. :2thumbs:

I'm doing my 8N Ford over to 12 volt right now.
It seems the GM alternator is the easiest way to go. I'd be interested in viewing a viable schematic with the Mopar alternator.

Check out farmallcub.com...they have a wiring diagram for converting the Cub...your "C" should be about the same...

i used a one wire gm alternator on my h and had the local alternator/generator guy change it over to 6 volts...i love it
Daddy ran whiskey in a big black dodge
bought it at an auction at the masons lodge,
Johnson County Sherriff painted on the side,
just shot a coat of primer then he looked inside,
well him and my uncle tore that engine down,
I still remember that rumblin' sound.....

And the 6v starter hasn't melted yet?
nope not yet.works way better than when it was a 6 volt system. :2thumbs:
I do agree on another post the gm alternator would work better if you want to keep it under the hood.Man is it tight under there.

Nothing wrong with the 1 wire alternators, and I've never heard anything about them causing batteries to not last as long.

Another option would be to use the old generator, put an 8 volt battery in and up the voltage regulator to match the battery. simple and it works. I've done this one to many old 6 volt system cars. This helps if you're just wanting a little extra umph for starting.

I just finished my tractor wiring harness this past weekend.
Only change I made was putting the resistor between the coil and the distributor.
And man...does it ever work nice now! I've even got HEADLIGHTS!!! Woo hoo!
I made my own terminal block out of a chunk of plywood, with two isolated steel bolts through it.
Total cost (less alternator): $15.78

If you did change to the 12 volt system and didn't change the coil, you might want to put that resister between the coil and the switch or you'll be changing coils every few months.

Yeah, I used a 12v coil...an old one I had kicking around.
My uncle recently gave me an electronic conversion module he had. So the next project on the list is to see if I can replace the points with electronic pickups.
Then, I'm also considering using a fuse panel I got out of a 1985 Dodge pickup.
