I know; the Mallory diagram doesn't make sense to me, especially that "all other wires" part that are connected to the (+) of the coil. In our case, that could be seen as the electric choke, and that wouldn't have been right since it would have only gotten 9 volts.

I am probably going to replace my old Mallory ignition module (ten years ago model) with a newer model, but it is still designed to be used with a ballast resistor. I notice on the PCM diagram, it shows a "bypass" for Ei (which I guess is Electronic ignition) on the resistor, but that's not always going to be a good idea - like in your and my case.
We need the resistor.

In any case, glad you worked it out.
