: : : I NEED SOME GUIDANCE OR DIRECTION ON THE BEST WAY TO CHANGE OVER TO 12 VOLTS ON MY '41 WC-12. HOW DOES THE POSITIVE GROUND AFFECT THIS CONVERSION?
Jim, I want to convert my '55 PW to 12 volt. How did your project work out? Did you go with the Chev alternator? How about the gauges?
I'd appreciate seeing a posting here on the forum on what worked for you (or anyone else for that matter!) Thanks
: WC-53's and WC- 56s and 57s were 12 volt negative ground to begin with according to the manual I have. Vintage Power wagons did offer a kit for the 12 volt conversion.
: : If yours was set up Pos ground then you will have to swap terminals with the wires on the ammeter, switch coils- hooking the wire from the switch to the + terminal of
: : the 12 v coil. depending on what sending unit (2 wire or 1 wire) you have, you might have to switch places with the wires on back of the gauge. A resistor is needed in the
: : hot wire going to the gauge if you use the 6 v unit. 3/4 WC's used the round S-W type of gauges making a swap to all 12 v easy. The 6 v starter seems to hold up well
: : using 12 v. GM type internal regulator alternators with a "one wire " conversion are easy to put on,
: : common and cheap (relatively). I like them anyway.
: THANKS FOR YOUR HELP, CHRIS. DO I NEED A RESISTOR AT THE DISTRIBUTOR OR WILL THE POINTS/CONDENSER HOLD UP WITH THE 12 VOLTS? ANY PARTICULAR YEAR GM ALTERNATOR THAT YOU PREFER?
