Still struggling- Farmall M

Posted by fisherman on November 25, 2005 at 07:16:38 from (206.104.152.226):

I’ve really had a lot to learn about electrical and wiring and a lot more to go. Please bare with me and my learning process because I know you get this same questions alot(John T, El Toro, Cowman, everyone).

I don’t really want to convert this over to 12 volt unless I’ve ruined some parts and just keep this tractor as six volts. For several months, since I’ve bought the tractor, its run just fine. The battery that was on the tractor it was a 12-volt (24-5). Never had a problem.

This is what continually gets me confused whether this tractor has been converted to a 12-volt or if a ballast resistor is installed otherwise why would it work on 12-volt (Like I said, electrical is not my area)?

How it started:
I checked the lights and they were all burnt so I changed them. The burnt bulbs were 1 light wire strand and the new bulbs had two wires for dim and bright. After changing the wires to the top lights and the bulbs- everything worked great, lights worked and the tractor started. Later that day it just didn’t start.

Next thing. I Simply pop the foot starter and the battery cable on the positive side of the battery popped. The starter did move or click.

After looking through the wiring diagrams by Bob M, my tractor looks closest to “Farmall H/M stock 6-volt generator w/cutout relay and magneto ignition” but there is a plate mounted on the generator and the wiring around the generator looks more like the one for “Farmall H/M stock 6 volt -voltage regulator mounted on generator and magneto ignition” but I do have lights.

The generator says remanufactured 6 volt and the plate that sits on top of the generator has a spring coil (sits vertical closer to the belt). Is this the voltage regulator? The electrical tabs that the wires connect two are red (if that means anything)

I went ahead and attached a battery to measure electrical currents. I have current to the to the generator even though the wires are exposed. No currenat all to the starter or the magneto. The lights are working.

At the foot starter there are two bolts that the battery and the starter cable are attached too. The bottom one where the starter wire come out, has no current and it turned red the last time I hit the foot pedal (ignition).

Yesterday everything was closed so today I was going to try a new six volt battery with 00 gauge battery cables. Is this the next place to start? Also, it was mentioned to me in a previous post to polarized the generator? Is this still needed?

I appreciate your time very much along with suggestions- Scott
