How to Convert a 6 Volt to a 12 Volt Regulator

Remove the negative battery cable from the negative battery terminal. This cable should be black and run to the frame of the engine bay. Remove the positive battery cable from the positive terminal. This cable should be red and connect to the generator. Unthread the nut attaching the positive battery cable to the generator. This cable is the only one running between the battery and the generator. Unthread the nuts connecting the wire running between the generator to the regulator. Detach the wire running between the regulator and the coil by unthreading the nuts.

Unbolt the regulator and the generator from their respective mounts with a wrench and a socket set. Turn on the grinder. Place the corner of the grinder's wheel on the weld that attaches the generator mount to the frame of the tractor. Grind off the weld. Grind the 6 volt regulator mount off the frame of the tractor as well. Weld the 12 volt alternator with the regulator mount onto the tractor in the same place where the 6 volt generator sat.

Bolt the alternator and regulator onto the 12 volt mount. Take the positive wire running from the coil to the terminal and attach it to the alternator with a nut. Attach the positive battery cable to the alternator. Reattach the negative battery cable to the battery terminal and then attach the positive battery cable running off of the alternator to the positive battery cable.
