Elec woes, crank, no start after running then parked.

Flipping thru elec notes I stumbled on this info I copied from SMP. The RU11 resistor I used is listed(orange highlights), it states to use with UC12X coil(I've tried UC12). Not sure what differences between the 2 are? It also states "WITHOUT STARTING BYPASS CIRCUIT" isn't that what the ballast resistor achieves?

Not sure what they mean WITHOUT STARTING BYPASS CIRCUIT? The Ignition 2 circuit which bypasses ballast and sends full battery voltage to coil only comes into play when key turned to Start position? So why would that have anything to do with ballast why ballast is bypassed? And do some mopars, maybe older models, not have an Ignition 2 circuit?

It sounded like voltage to coil stayed consistent while it was running and until died so I don't think its a ballast resistor problem. And 9 volts + side of coil is right where it should be too....
