Thread: 6volt to 12volt

Tweet

Ok soon i will have the body off the 54 i need to know exactly what i need and what to do to change it to 12 volt . Also will it become a negative ground because as of right now its positive ground. Thanks

ohh yea i meant to say that when the body goes back ill be hooking up the 12 volt

i work and work and still dont have time for my cars

if i was doing it id have a single wire 12v alt, a good 12v bat. change all the bulbs, inatall all new gauges. if for some reason you need to keep a 6v gauge(or whatever 6v)you can get a resistor and put it in line so you wont burn the 6v gauge up. the starter i guess will be 12v, im sure you could update the heater motor, if not use the resistor. everything should go back neg. ground. if your keeping the same starter ive all ways hooked the 12v stright to the 6v starter, sure makes it turn faster and should last awhile driving it just sometimes.

The 6v starter should do just fine if it's in good condition. Here's a link to an article where the guy did a whole rewire on a Plymouth.http://www.rodandcustommagazine.com/...5_0310_rewire/ If you don't need to rewire, there's still some good pointers in there. I've used the "Runtz" resistor before, works great. See www.speedwaymotors.com

I think if change to neg ground you'll need to change the wiring around on any org gauges you use and the heater motor other wise they will work backwards

thank guys im only doing the 12 volt for reliability . I know ill be driving the 54 fairly regularly so its gotta be reliable

I work and work and still dont have time for my cars.

thanks Bob, i needed that info also for the 50 plymouth i got the wife....joe

Hey guys
Just saw all your posts about the 6 to 12 volt Plymouth deal. I had a 52 ply and now have a 49 Ply. ,both were 6 volt . If everything is good starter, WIRES., battery etc the 6 volt stuff works fine. I drove the 52 EVERY day for 2 years and it didnt start just 1 time[out of time] and 20 degrees outside. I dont start the 49 for sometimes 2 or 3 weeks and have to crank it for quite a while with no problem. A fork lift battery to fit , a 1 wire alt. 6 volt rebuilt starter and large battery wires and you are good to go. You will replace these things anyway. Just a thought for you.

6 volt can at times be reliable and I'm keeping my '51 Chevy 6 volt. Light bulbs and ign parts are often hard to find and have to be ordered so a failed ign condensor or coil could have the car on the side of the road for a day or so, that's most people's reason for converting. I run a TSC 6v tractor battery in mine.

It's a fairly easy job, I did my 54 Savoy and kept all orig. equipment with the exception of the generator(made my own alt mount). One wire alts are overated. If ya have more Q when the time comes I (am sure theres more) would be happy to help with specifics.
