If the contacts are stuck the power will feed back and kill the battery. For the generator to charge, the contact points in the regulator need to close to complete the circuit,when the battery is charged the regulator breaks contact and it stops charging so the battery doesn't over charge. Hi again ,before you start to rewire the tractor have the generator checked to see if it is charging,also take the cover off of the regulator and see if the contact points are stuck together,and if they are closing so it will charge. Ed S : : : I am looking for a wiring diagram for a Farmall M with a generator, distributor, 6 volt, and positive ground. I just got the tractor, so I think that some of the wiring is wrong. My problem with the M is that when I have the tractor running, the amp meter shows a negative charge and the battery eventually drains to nothing. L : : I am looking for a wiring diagram for a Farmall M with a generator, distributor, 6 volt, and positive ground. The wire will usually be 10,12,or 14 gauge wire.

You can use crimp on ,or solder on wire ends. Hi L unless you have taken the wires off or it diden't have them when you got it ,just cut the tape ,or the mesh that holds the wire bundle together and trace the wires and replace them one at a time.

Also what paint is recommended for the silver and red? Ed S : I am looking for a wiring diagram for a Farmall M with a generator, distributor, 6 volt, and positive ground.
