Converting to 12 volts

Post by gmc1942artil »

I have acouple questions I have recently took apart a 1944 Tow truck. chevy. with a 216 in it. after ripping off the fton fenders I noticed the generator was a little bit bigger than the reg Chevy. after scraping off the oil on the data plate its says its 12 volts. I looked and the dist has a little white resistor or something inline.. my question is. whats that resistor and where to get another.. and do I have to put a resistor inline to the cab so I don;t blow my gauges and headlights out?? or do I convert everything over to 12 volts. which sounds like a pain in the ARS

The resistor is for the coil if you keep the original 6v coil

Buy new light bulbs. You CANNOT use resistors on them

oh ok thanks. do you know what resistor that is... I would think keeping a spare in the truck would be smart

A 12v internal resistor would be a better bet for a spare. That way if the resistor OR the coil fails (which they do) you have a spare. If you have to use the 12v coil, eliminate the resistor
