I’m looking for a spare ballast resistor. I have a 70 Duster 340 with Mopar electronic ignition. Does anyone know what Ohm values I need or a part number that will work?
Thanks for your help!
Stu. With a stock orange box, use a 0.5 ohm ballast resistor.

Assuming U are using the Mopar aftermarket factory system(#P3690426), orange box and stock coil(#02495531)... The ballast resistor is 1 Ohm, Mopar #P5206436. Just my $0.02...

Please correct me if I am wrong, but other than the early electronic ignition that used a dual ballast (one for coil and one for the ECU), it is not the box that determines the ballast resistor, but the coil rating. The coil you are using determines the ballast resistor rating. You are correct
