Re: 6v Positive Ground to 12v Negative Ground Conversion

Lots of good advice posted above, and I would like to add one more thing. You will need to reverse the leads on the new coil from where they were on the old one. The negative (-) lead goes to the distributor on negative grounded systems. JWL

Edit: You should be able to get by with running the ballast resistor on the coil without any switching devices. The resistor, like Fred says, will drop the voltage from 12 to 8 volts or so. This should provide an adequate amount for starting.
