Thread: Changing from 6 to 12 volts revisited

Tweet

I think about the only to issues you have with changing ground, is the direction of motors and function of guages. As to the motors, you could change the polarity internally and you're good. AS for the guages, you could replace them with some preiod correct units, or you could possibly isolate them and leave them positive ground. Also available, are specialty shops which can rebuild the guages to positive ground.

Thanks everyone. Those links have a lot of good information and I will have to spend some time going over them.

Finally found some 12 Volt headlight bulbs (halogen) for the Graham. I located them at a business in Australia "Classic and Vintage Bulbs" http://www.classicandvintagebulbs.com/
The owner Anthony Pearson was actually visiting the Hershey Swap Meet when I contacted him by e-mail and shipped them to me from there. Great guy to deal with and I highly recommend them for any headlight or bulb issues you may have.
