Re: Change to 12 volt negative ground Start with a the Generator, you can "convert" the original to 12 V 30A. with a 12V relay
Or buy a new Alternator that looks similar to an original. Then you have to change the Coil. If you have an original distributor, there is an adapter you can buy so you can mount a separate 12V ignition coil. Then there is the lamp's that need to be 12Volt. If you use the original amp meter, you need to switch the cables positions, so it shows charging and undercharging right |
Re: Change to 12 volt negative ground Some information here: http://www.how-to-build-hotrods.com/hot-rod-wiring.html
There are a lot of past threads here on the Barn about voltage reducers for the gauges. |
Re: Change to 12 volt negative ground Save your money, get some 1/0 cables and it will spin
like 12 volts. G.M. |
Re: Change to 12 volt negative ground And, there are 12 equivalents for all bulb types in your car. The horn(s) will probably still work but be a bit screechy.

I've been pondering the same change on my '35 and I'm really interested in learning what are some of the several reasons motivating you? |
Re: Change to 12 volt negative ground The best change would be a 6 volt alternator and larger cables. G.M.

Re: Change to 12 volt negative ground If your wiring is still original I'd just rip it out and put a new 12v universal harness in the car. Speedway has them for about $150.

Lots of good info in this.

Re: Change to 12 volt negative ground That six volt starter will work, but I snapped a couple of Bendix springs during the 13 years I ran one on 12 volts. Chap

Re: Change to 12 volt negative ground I have been involved in a fender bender apparently young drivers don`t under stand hand signals so i want to install turn signals,electronic ignition found out you are so limited with 6 volt
|
Re: Change to 12 volt negative ground There are 6v turn signal units available. Might consider a third brake light as well. There are a lot of modern accessories that work better with 12v neg ground.
|
Re: Change to 12 volt negative ground Turn signals work at 6v...points ignition may need a light tuneup each spring but seldom fail in a catastrophic way...
If your 6v system is fine just upgrade with turnsignals and be back on the road again... |
Re: Change to 12 volt negative ground 6volt OPTIMA battery is you friend.

Re: Change to 12 volt negative ground Plus, I make a device that alows you to run any 12 volt negative ground commonly available tachometer of a 6 volt positive ground vehicle. i am also running a device that alllows just about any 12 volt negative ground accessory to be run on 6 volts positive ground. I have a prototype that allows a GPS, Bluetooth for my cell phone, a backup camera, and a CD player to run in my '51 as we speak.

Re: Change to 12 volt negative ground I have run my restored 1933 roadster on 12 volt for over 40 years.
same original coil - starter & generator. the generator will charge (just adjust 3rd brush to wanted amp charge ) I use an additional ( common 12 volt ign resistor ) for ign change bulbs to 12 volt . horns work better . switch wires on am meter . I use a small 12 volt battery in a battery box I make ( also sell ) that makes the battery look like a 33 battery. My lights are brighter --- my car starts faster all in all best of both worlds. |
Re: Change to 12 volt negative ground There is a reason Detroit and other car manufacturers switched to 12 volt many years ago. I switched my '48 30 years ago and never looked back. Wouldn't even consider 6 volts.
