I'm a moron, I admit. I removed my old harness on my 50 GMC (6V, positive ground) and was planning a 12V conversion,so I bought a new harness. Now plans have changed and I want to stay with the original 6V setup. Of course, my old harness is long gone. Can I use the 12V harness in a 6V setup? Sorry, don't understand watts from amps from volts. HELP! Thanks.

no,six volt wiring has to be twice the size.if the harness was made only for 12 volts it probably has smaller wires.

FredB,

From whom did you buy the wirining harness? Did you specify 12v?

I bought it from Jim Carter.., no, I did not specify 12V. But like an idiot, I did specify alternator (hey, at the time, it seemed like the right idea.)

FredB,

If you bought a harness for a 1950, call Jim Carter and ask if it will work with a 6v GMC. My guess is that you will be OK with the new harness as long as you use the larger 6v battery ground strap and starter cable.

Too bad about the alternator set-up - maybe someone else will have advice on that.

I am sure that if you talked to Jim Carter, he would try to help you out. If your alternator harness is unused, he may well let you exchange it. It is worth a call..

It should be fine , just make up a three wire sub harness for the generator to regulator , the repop harnesses all come in the same diameter wires . slap that puppy in and go drive your Jimmy .
