One wire alternator problem

So your saying that if i connect both wires that go into the ballast resistor together (basically bypassing the resistor) that will give me a solid switched 12v source for my MSD box?

Yes, here's the thing

The "run" wire and the brown "bypass circuit" (known as IGN1 and IGN2) come from the ignition switch.

The blue "run" wire GOES DEAD during the time the key is twisted to "start."

The brown bypass / IGN2 originally hooked to the coil side of the ballast and supplied full battery voltage to the coil during start/ cranking.
