You put the resistor in the circuit that FEEDS the coil...cutting the 12V input down to the 6V that the coil can handle. You are NOT using the resistor to cut the voltage below 6V.
If you keep your electrical system 6V, there is NO NEED for a resistor in the ignition circuit. AND if you switch to a 12V coil, there is no need to have a resistor in the circuit.
YOU ONLY USE THE RESISTOR WHEN USING A 6V COIL WITH A 12V ELECTRICAL SYSTEM...AND THEN ONLY TO REDUCE THE INPUT VOLTAGE TO THE 6V COIL DOWN TO THE 6V INPUT IT WAS DESIGNED TO HANDLE. YOU DO NOT USE THE RESISTOR ON THE OUTPUT [DISTRIBUTOR/POINTS] SIDE OF THE COIL.
