Now, let's focus on the areas that you need to change. The ground strap will need to reach and have the correct end to connect to the negative post and the cable to the starter solenoid will need to reach and have the correct end to connect to the positive post of the new battery. Things like the ignition coil, amp guage, wiper motor, heater motor, etc.Īlso the battery cables will need to be changed or modified. Start be reversing the power wires to anything that is polarity conscious. So, if you have a positive ground, you need to do a few things first. Second, figure out if you have a positive or negative ground. So, the wiring will live happily with 12v. Changing to 12v cuts the amperage load approximately in half. It's heavier because it has to carry more amperage. It's easier and cheaper to do it all once than to change over, fight bad wiring, have problems, then have to do it all over a second time.įirst, if you're wiring and your switches are in good shape, then so are you!Ī 6v wiring system and switches are more than enough to handle 12v. There is no sense putting all this work into changing over if you're still going to get shorts and take a chance on burning down the car. If your wiring is frayed, split, or cracked, start over. However, before we get into this project, look over your wiring. The benefits are easier starting and greatly improved headlights, as well as the ability to add 12v accessories.
