It works!!!!

I mentioned this on the Farmall forum a couple of weeks ago when I started the project.

Earlier this fall, I bought a 1944 H Farmall to go with my other two H's. It's proven to be healthy mechanically, but the wiring was atrocious, with insulation falling off, bare wires, etc. I decided to rewire it.

When I tore into it, I found the whole system was a cobbled up mess. It had a new style generator with the fixed third brush and a voltage regulator, but the light switch and the rest of the wiring was appropriate for the older style generator with an adjustable third brush and cutout relay. Some of the wires weren't even connected, and the lights didn't work.

I decided to start over from scratch. I pulled all of the old wiring off and ordered a new voltage regulator, new style light switch, along with some woven plastic sheaths to run the wires through, plus a fuse holder to mount in the ammeter panel. Armed with the proper wiring diagram, I built an all new wiring harness.

I was done far enough yesterday to try it, and it all works like it should.

My plan is to swap my loader from another H onto this one, and do some serious work on the one that has the loader on it now, including all new wiring. That one has been in the family since 1957, so it might even deserve a new paint job.

Good work pays off well. Nice. Jim

That's the way to do it!

Many people are so intimidated by wiring they won't even try.

You did your research and conquered it!

Tractor wiring on older tractors is pretty simple. As long as you have the wiring diagram it should be pretty simple. Or if the old harness is complete and not all cobbled up you can take it apart and just copy it.

I redid a Farmall M a few years ago while converting it to an alternator and 12 volt. Built a new harness from scratch. I use the Delco 3 wire alternator.

How do you identify the two generator types?

Externally, a generator with a cutout relay is tapped for the relay to screw onto the top of the generator. A generator for a later style system with a regulator under the gas tank will not be drilled and tapped.

For a system with a regulator on top of the generator I'm not sure without taking the band off the generator and physically looking at the third brush to see if it's permanently fastened to a plate with the other brushes or if it can be loosened and adjusted.
