If it is a "can" style coil, it has to have 6 volts to the coil (no ballast resistor). It is simple to bypass the resistor, just move the input wire to the output side so both wires are on the same side of the resistor. You can check the coil to determine what you have, the resistance across the two terminals should be around 1.5 ohms. If that is what you have, no resistor should be used in the circuit.
