Technical 12V Conversion ??

Use a Ballast resistor or just get a 12v coil ? Also what effect with the 12v have on the stock points ?

 

Without a resistor or resistor wire 12 volts will burn your points. There is no difference between 6V points and 12v points. Rusty O'tool says you don't have to change the coil because you are using a resistor, he's pretty smart. I have always changed the coil but like I said Rusty is pretty smart so unless someone comes along that I think smarter I would be willing to give it a try.

I always change the condenser, I have thrown 12v at 6v condensers and fried them. it is always a good idea to keep a spare condenser on hand if you are running points anyway.

When you tune up and eventually you will get blue streak platinum points. Just advice from an old fart.

 

Radio and gas gauge will need to see 6 volts if that is original. Heater and starter motors don't care. Dash lights will be very bright and then die ditto for head and tail lights. Wiring is ok to be left alone.

 

You could also get an internally resisted coil.

 

If your 6v car did not have a resistor or resistance wire, then you have a 6v coil and it will work fine with a resistor.

Some 6v cars used a 4v coil and a resistor, in that case you would need a bigger resistor.

 

I used an internally resisted coil when I did the '40 Stake truck.

All these suggestions will make it work. In the long run you'll have less headaches.
