Tell me about your ballast resistor failure.

Yes , I have an original 3656199 Dual Ballast Resistor in my stash for electronic ignition
Came off a factory 1973 Dodge Charger

It also is .5 OHM on the coil side of the Dual Ballast Resistor

Then that part # was replaced or superseded with the Dual Ballast Resistor that I have pictured

Same part #s , different OHM Ratings on the coil side of the Dual Ballast Resistor clearly in pictures

.5 OHM open
Normal Side in that diagram below

"On one side is the half-ohm ballast resistor that is the same as in a breaker-point sys-
tem. It maintains constant primary current with variations in engine speed."

1.2 OHM sealed later on , you mentioned 1976

Thanx
