Upgrading Alternator

Put your wiper motor on a relay and use your original wiper wireing to just turn on the relay. That way you are pulling the volts right from the battery, not through the harness. If that works out for you, make relays for your headlights too. You'd be amazed on what 2 volts does to the output of your lights. Your original alt is about 35A. Get yourself a rebiult tested alt, and check your old points type regulator. They make electronic ones now that look like tht old ones, or you can upgrade to a isolated field squareback alt and electronic regulator. The original blue wire goes to the 1st (right) terminal of the electronic regulator and then on to the first field of the alternator, the other terminal of the regulator (bottom of the triangle) goes to the second field. They put out about 2X the amps of the old round ones. Might want to consider upgrading your main run to the battery to an 8g wire. That or a smaller pulley on the alt and a larger pulley on the crank.
