I had an ignition coil fail on me recently and the only one I could find to replace it at short notice was supposed to have a resistor used with it. Fortunately, someone there knew how to connect it, Is it just connected in series with the coil? What is the point of it anyway? Is the coil actually made for a lower voltage and the resistor is left out of the circuit while the battery is cranking the motor and therefore only able to deliver a lower voltage but drops the voltage to the coil during normal running?
I've converted to 12 volts.
