Bingo!! The lowered voltage extends the life of the points, nothing to do with overheating coils. There are 12v coils in all our cars unless someone wanted to get more spark the old school way and installed a 6v coil. Just run a jumper wire across the two leads on the back of your ballast resistor to get 12v to the coil and still look stock. Jumping a bad resistor recycling it is better yet! Now running 12v will shorten the life of your points unless your running a Pertronix unit or something like it that is designed to run on a full 12v because the reduced voltage from a ballast resistor is getting close to the fail voltages of their system. Pertronix systems as well as others are designed to run with a low resistance 12v coils, as opposed to a standard high resistance coil that will burn the Pertronix unit and others, out in the end. That is why I always install Pertronix units and Pertronix coils as a set and have had years & years of trouble free operation.

I believe the ballast resistor was also there to protect the points from having 12V through them constantly.

I also believe a 12 volt coil will eliminate the need for a ballast resistor. Our older Dodge systems are made to start with 12 volts to ensure it will start. After starting when the key returns to the run position it feeds power through the ballast resistor dropping the voltage to the coil to 6 volts. If you bypass the ballast resistor it will run but the constant 12 volts to the coil will cause it to eventually overheat and fail. If you take the ballast resistor out or bypass it you need to replace the coil with one made to operate with a constant 12 volts. Pertronix makes a 12 volt coil some of the other manufactures also have 12 volt coils in there cars they are not hard to find and not to expensive.

I can't testifie about the Mopar electronic, but for points or Pertronix, you can eliminate the ballast resister by going to your parts house and asking for a coil that says right on it, "no external resister needed" It should be on their shelf. They must have the resister built right into the coil. .....................................MOOn Tuesday, June 11, 2013 9:08:24 AM UTC-5, Roger Pettigrew wrote:
the only way to eliminate the ballast resistor is to go with a complete aftermarket ecu system, such as MSD or pertronics, as well as a different coil
I know it has been covered here before, but with advancing CRS (can't remember s***) on my part,
can someone tell me how to eliminate the ballast resistor ? I have the MoPar electronic ignition
with the orange box, and want to eliminate the weak link in the system if possible. Thanks, Warren.
