      Polarization of the generator should take place after any of the following events have occurred:

      1. The battery is replaced or disconnected;
      2. The generator is replaced or serviced;
      3. The regulator is replaced or serviced.

      If any of these events occurred, don't start the engine until polarization is done. The
      polarity of the generator must be set to match that of the voltage regulator.

      Make a jumper wire (14 or 16 gauge) long enough to reach from the battery to the
      generator. Solder alligator clips onto both ends.

      To polarize a generator on a 6V positive ground system, attach one clip to the A terminal on the generator. With
      the other clip, briefly for only a split-second (or a spark occurs) tap the negative ( - )
      terminal on the battery.

      It's not the regulator but the generator that requires polarizing, but you can do it from the regulator. There should be a momentary jump between the GEN terminal and the BAT terminal.

      We often hear the phrase "polarizing the regulator", but the process actually is to polarize the generator by causing the steel screws holding the field coils and shoes in place to have a slight magnetic charge so that when the generator begins to function it
      will energize the coils to produce voltage with the matching polarity of
      the car. The shoes themselves will not retain any magnetism induced because the shoes are made of iron which has no residual magnetism qualities.

      Failing to polarize a 6 volt regulator can cause damage to the entire
      electrical system of a vehicle or machine. If the battery dies, or if the battery or regulator is disconnected from the electrical circuit, the
      regulator must be polarized before it can turn the engine over again.

      Polarization matches the electrical memory of the regulator to that of the
      generator. The voltage regulator is connected by a positive wire to the generator. Clip your jumper wire to your battery terminal. Find the terminal marked
      "F" (for field terminal) on the regulator. Touch the free end of the jumper wire to the "F" terminal twice for less than a second each time. You will have polarized your regulator.
