Convert from 6 to 12 Volts

One of the most frequently ask questions we get is, "How do I upgrade to 12 volts". The 12 volt upgrade is probably the easiest and least expensive project for the do-it-yourselfer. Before we get into the project, we  would like to share a few of the most frequently asked questions.

Q: When I go to 12 Volts will I have to change my wiring or go with a larger size wire?

A: No, if your wiring is in good physical condition, there is no need to change wire sizes. Load amperage will drop by approximately 50% when changing from 6 to 12 volts.

Q: Will I have to change the starter to 12 Volt. ?

A: In most cases you will not have to change the starter. If a starting solenoid is used to engage the starter, it will need to be changed. If the starter is in poor condition with worn bushings and brushes, the upgrade to 12 volt may hasten it’s failure. In most cases it improves starting.

Q: I have a positive ground system, what do I need to do when changing to 12 volts?

A: Because your charging system will have to be upgraded, a negative ground is required. Start by reversing the load wiring on any electrical device that is polarity conscious. Some of the items that are polarity conscious are the amp meter, starter, ignition coil, wiper motor and heater motor, etc.

GETTING STARTED

Ok. lets get down to it. As an overview to this project we will cover the four basic areas needed to complete the project. These areas are the Charging System, Instrumentation System, Starting System and Lighting System.
