If your using a complete MSD replacement ignition system, then the coil is supposed to be driven directly from the MSD control unit (see http://www.rowand.net/Shop/Tech/images/MSDWiring011.jpgAs such, the ballast resistor should not be in the circuit.Below is a block diagram of the standard dodge electrical block diagram for the associated circuits.
