Re: Coil wiring question

WILLIS,

When your car was changed to 12-volts was a ballast resistor placed in the circuit between the ignition switch and the coil? 12-volts without a resistor will overheat a coil and lead to premature death to it and distributor parts. Some coils come with an internal resistor in which case an external one is not needed. Make sure which type of coil you have and whether an external resistor is required.

When you car was changed to 12-volts was the ground also changed to negative from positive? 6-volt Packards were positive ground. If a car has a negative grounded electrical system, the negative terminal of the coil (primary lead) is connected to the distributor, and for positive ground, the opposite.

I hope this helps, but you may have other problems. Keep working at it and asking for help, you'll get it fixed, sooner or later.
