They may have different operating voltages when they warm up.
Most after market electronic ignitions do not require a ballast resistor.
You didn't mention if yours requires a resistor.
The ceramic block one without the steel bracket looks like the one mounted on my cars firewall which was originally a points car.
Thanks a million, never knew that! The triangle one has a 1.4 stamped on it.The OHM value is usually stamped on one of the terminals.
I think "measure the resistance of...." is the phrase you are groping for.You would need to OHM them

ohm, abbreviation Ω, unit of electrical resistance in the metre-kilogram-second system, named in honour of the 19th-century German physicist Georg Simon Ohm. It is equal to the resistance of a circuit in which a potential difference of one volt produces a current of one ampere (1Ω = 1 V/A); or, the resistance in which one watt of power is dissipated when one ampere flows through it. Ohm’s law (q.v.) states that resistance equals the ratio of the potential difference to current, and the ohm, volt, and ampere are the respective fundamental units used universally for expressing quantities.I think "measure the resistance of...." is the phrase you are groping for.

Impedance, the apparent resistance to an alternating current, and reactance, the part of impedance resulting from capacitance or inductance, are circuit characteristics that are measured in ohms. The acoustic ohm and the mechanical ohm are analogous units sometimes used in the study of acoustic and mechanical systems, respectively.
I think the early add on kits had the dual resistor and 5 pin. The sort of mimicked the factory style. Later were rewired and has a single resistor and 4 pin as I recall.Don't know which 'original' Chrys elec ign is being referred to in post #13, but I bought the 'original' Direct Connection [ forerunner of Mopar Performance, part #s started with a P, P3690422 ] elec ign conversion kit in the early 70s. I still have the instruction sheet. It came with a 5 pin ECU & dual bal res, 0.5 ohm & 5 ohm. All the early 70s Chrys cars I saw in this country that had factory elec ign had dual bal res....
