Remove the negative battery cable from the negative terminal, then remove the positive cable from the positive terminal.
Unscrew the nut from the "F" terminal -- field terminal -- and place the eyelet of the voltage regulator's "F" wire over the terminal and screw the nut back on. Tighten the bolt with a socket.
Attach the "F" wire to the regulator's "F" terminal.
Un-thread the nut off the "A" terminal -- armature terminal -- and place the eyelet of the "A" regulator wire over the terminal. Thread the nut back on.
Connect the "A" wire to the regulator.
Rotate the nut off the "G" terminal -- ground terminal -- of the generator, slide the eyelet of the regulator's "G" wire over the terminal and replace the nut. Tighten the nut and attach the other end of the wire to the regulator.
Reattach the positive battery cable to positive battery terminal, then attach the negative cable to the negative terminal. Clip your jump wire to the "F" terminal and touch the positive terminal on the voltage regulator.
Count to two and remove the jumper wire. You have polarized the generator.
