1950 C

Eric187 · Jun 11, 2014

I recently bought a 1950 Farmall C, and I was checking into getting it converted from 6v to 12v. The first guy I talked to said he would do it for around $800, that seemed a little steep. I am very busy this summer with the farm and don"t have the time to to the conversion myself, I will have time this winter, but I am having some starting problems with it and would like to use it for cultivating. The previous owner said that the "brushes" had gotten rusty because it sat for a few years and condensation rusted the inside of the generator.
Thanks in advance for any advice, I am sure I will be in here a lot over the years to come as I get to know my first tractor.

Buy a 12 volt coil and put a 12 volt battery in it. Just plug in a float charger each night when you are done and it will be fine until winter. Then, this winter buy a $30 Delco 10SI alternator (they really are that cheap) and search the archives here. There's enough information on switching them to make a hamster capable of getting it done. Just put a battery and coil in it for now. Don't turn on the lights until you get 12 volt bulbs in them.

I bet he would! Shoot I'll do it for 1/2 of that.

It is only a half hour job to fix the generator & you are good to go. They start easy on 6 volts.

You can't spare a couple hours to do the conversion yourself?

The C is about the easiest one to convert because you don't have to do any fabrication work. The alternator will bolt right in place of the generator with a piece of all-thread, 4 nuts, and lock washers.

Wiring could not be simpler:
1. Take the wires from the BAT AND L terminals on the old regulator, and connect them to the BAT post on the alternator.
2. Connect a short wire from the BAT post on the alternator to the 2 terminal on the alternator.
3. Install a new 12V coil, swapping the + and - wires as compared to the old coil. The - wire should connect to the distributor now.
4. Run a wire from the + on the coil, up and over the engine. Connect a large diode from radio shack to the wire with the line end pointing toward the alternator, then connect the diode to the 1 terminal on the alternator with a short piece of wire.
5. Swap the wires on the ammeter so it shows charge correctly.
6. Install 12V battery, connecting the - post to chassis ground.

I have a 240U (same basic set-up) changed to 12V. My advise is to take the 6v generator to your local auto-electric shop and get it rebuilt... a lot cheaper in the long run.

Should be less than $200.
