To Polarize the generator, just take a short piece of wire, and short accross the "BAT" on the regulator to the "GEN" or "ARM" post of the generator, without the tractor running. It should spark when you do this.

The "BAT" terminal / wire should always be hot.

Assuming the tractor is wired correctly you can bypass the regulator to make sure the generator is charging by doing the following:

First: You have to have a good ground with both the generator AND the regulator. Use your meter to make sure you have both well grounded. If in doubt, run a dedicated wire from your battery ground to the regulator case. Also, make sure you have a hot battery, and the belt is tight.

Next: Polarize using method described. You should get a spark when you do this. If you don't something is wrong.

Next: With engine running, ground the field post to a good ground and see if it charges on the ampmeter.

Next: if it still doesnt charge, leave the field post grounded and jump the V.R. "BAT" to the generators "GEN (or "ARM") terminal. This completly bypasses the V.R. and if the generator is working, you should get a good positive charge on your ammeter.

If it still doesnt charge you have incorrect wiring, or a bad generator.

If it does charge, the problem is likely in the V.R.

If you re-wired the tractor recently, and the polarizing did not do it, you may have to reverse the wires on the ammeter.

Post back and let us know.
