Correct ballast resistor

The Accel Super Coil has a primary resistance of .7 Ohms
Similar to the MSD Blaster 2 coil

Factory Chrysler coil has a primary resistance of around 1.6 Ohms

Chrysler used the same ignition coil running there points distributors of the 60s/70s and a single ballast resistor with an .5 Ohm rating and that same part #ignition coil was used thru the mid 70s running the electronic ignition / ECU and a dual ballast resistor with an .5 Ohm rating on the coil side

Chrysler changed the Ohm rating of the dual ballast resistor to the coil side at 1.2 Ohms around mid 70s also
