Having trouble finding a one wire 12volt alternator to replace 6 volt generator. I'd prefer to purchase an alternator alone without a kit, I'm cheap.
Thanks,

If you're dead set on 12V why not just take your generator and regulator to your local rebuilder and have him set it to put out 13.5 volts. With the new LED bulbs you don't need a lot of amps to run your lights. BTW going to 12V not not a cure for poor compression and other starting ills.

Go to an auto junkyard, get an older model GM alternator, take it to a shop and get a self exciting regulator installed. Most older gm trucks and cars had them. Many tractor shops will know what you need. I don't like a one wire. Seems they need a certain speed to work and also won't work on a tractor that sets for long periods without use.

Most O'Riley and Autozone 10SI Delco rebuilt alternators are one wire but can be used as 2 wire. The real issue is what tractor
you are working on. A Hitachi 14231 alternator fits on the H and SuperH 300 more easily. It will likely be a 3 wire, but that is
not an issue. Jim

A 'standard' GM one wire alternator is available at just about any auto parts store. The last one I bought was about 55 dollars ,with a 10.00 core.Make your own bracket(s),rewire yur self.Easy,cheap,and best of all trouble free.I have 5(SH;M;SM,400;M400 hybrid) old farmalls with a one wire 'conversion'. They WORK.

I should've made it more clear, I'm already running 12volts in an H and it runs like a top. It just still has a 6volt generator in it.

Forgot to mention it's an H

Any alternator in particular that would fit under the hood of an H?
Take it from my experience this is my Farmall H. Install the Hitachi 14231 available at any auto parts store. Alt was used on 1970's Datsun pickups I think. That is a straight edge along side in the picture you need the smaller Hitachi or similar for hood clearance or hack a hole in your hood.

Is that a diode there on the valve cover?

The unreliability of current day replacement mechanical regulators is one strong argument for the reliability of an alternator with built in solid state regulator.

Ebay has several good one wire Delco alternator sources for around $60,get one that has a double pulley that extra pulley groove makes adapting them on old tractors easier lots of times.
I've put on about 20 of them on various models tractors and have found about 99% of the negative comments on one wire alternators to be B-S.

Here is a pic of my Farmall C. Alternator isn't mounted under
hood. I used a 3 wire. I ran both the two smaller wires through
ignition switch so all the power is removed from alternator. I
like to use an idiot light. Many times an idiot will pull on the
kill switch to kill spark from Mag and forget to turn the key
off.

This setup is the way to go! I've done this many times. Flip the bottom bracket around and cut some 1/4 inch pipe for spacers, or use washers. The same belt works as well as the top adjustable link.

I used a hitachi alternator for a 78 datsun pickup. it fit under the hood without cutting it, wires just like a delco, and i was able to use the original brackets (with some modification). I used pipe as
spacers on the bottom bracket. All thread and nuts/washers works well, too.

I'm with Delta on this one. The delco will fit you just have to build your own bracket. And you don't have to cut the hood. I put one on our H. Might have to change the belt though. Been a few years since I did it.
