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?
