Repolarizing Your Generator
If your tractor has been stored without a battery for a while, or generally has charging problems, you may need to repolarize your generator. You need to do this anytime the generator or regulator has been removed or the leads disconnected. This is a really easy procedure, and requires only a short piece of wire. First, make sure that the positive terminal of the battery is grounded. Then, momentarily connect a jumper between the "BAT" terminal of the regulator and the "A" terminal of the generator. Hold the wire on one end and just brush it across the other - you should see a spark. If you do see a spark, you're done. It is that easy. Remember, don't connect the wire, just momentarily touch it. And make sure you have the right terminals at both ends (they should be labeled). If you do the wrong ones you're likely to fry your regulator.
