What model coil is it??
Accell Super Coil Resistor?
I just finished wiring my 66 Galaxie converting from points to the Duraspark ignition. I followed the wiring diagram on Mustang Steve's site which has the Pink resistor wire removed and replaced with a wire diectly to the coil supplying a full 12 volts. I am now wondering does the Pink wire drop the voltage to much for the Accel coil but enough for the old points system. I am assuming the Accell 150001 resistor reduces the voltage enough to keep the coil cool but still operate and the original wiring would have prevented that.
Also is there a sutable replacment resistor that I can pick up at a local auto store instead of ordering a resistor on line, my friend gave me the coil but no resistor.
I was reading the Coil information on line and it said to use the ballast resistor along with the cars resistor for points applications, does that mean that no resistor is required if using a Duraspark set up or just the .85 ohm resistor that is not original to the car?

That's kind-of a loaded question...I just finished wiring my 66 Galaxie converting from points to the Duraspark ignition.

The ignition system will perform better with no resistor in the circuit. However, the Duraspark electronics will overheat and stop working, (intermitently or all the time), if no resistor is used for a long period of time.
1. Strictly temporary usage as in a racing type scenario should usually use no resistor.
2. Continuous usage environments should have 1.8 ohms or greater resistance in the coil circuit; (that's 1.8 ohms TOTAL, including the primary coil windings), to keep that circuit from overheating.
Using that coil with a Duraspark, about a 1 ohm resistor is usually fine for street and continuous usage; by-paas that resistor with a toggle switch with it's own circuit for racing.
