Voltage to coil

But if I put just the one dark blue wire and the brown wire on the resistor and still got 12 volts, doesn't that tell me that I am not losing the voltage in the block or on the ignition? Is the coil pulling too much? I thought maybe it was because we had hooked up the electric choke to the coil, but that only made the coil side go from 4 something to 5 something.
