Common questions

Where are the resistors on a Mopar ignition kit?

Where are the resistors on a Mopar ignition kit?

Some resistors are fully potted while others leave the resistor wire exposed on the back side. Full potting keeps the internal wire protected and helps dissipate heat. Above: The Mopar officially licensed ignition kit was first up (#440-428).

What’s the voltage on a Mopar race car?

Voltage is held at a constant 13.5 volts. For race applications only. For restoration or repair, Mopar offers this factory reissue of the Voltage Regulator, as used on muscle cars of the early 1970s. The regulator is black, with the original Mopar part number imprinted in yellow. Contains modern electronics.

How does a Mopar engine work for performance?

The primary uses centrifugal force with a light springs and the secondary works with higher RPM; it uses a heavy spring with a loop in the end. Mopar Performance introduced the capacitor discharge conversion kit that included the new electronic distributor, an ECU (electronic control unit), wiring harness, and ballast resistor.

Can a breaker point Mopar be converted to electronic ignition?

Mopar Performance (the old Direct Connection) sells a very nice kit for older breaker point Mopars to convert to true Chrysler electronic ignition. Many muscle cars have had this installation done over the years and is widely accepted as being correct and not considered a modification.

How does the rotor work on a Mopar ignition?

A cam with equally spaced lobes opens and closes the point contacts. Each time the points open, the coil releases spark to the rotor, and the rotor distributes that spark to the lucky firing cylinder via the plug wire. The downfall is that the cam lobes, point contacts, and rubbing blocks wear over time.

What are the requirements for a Mopar distributor?

One or Roy’s requirements to ditch the dual-point was that the new distributor had to fit right in with the vintage (i.e. unrestored) look under-hood of the big, orange B-body. That meant no flashy billet bodies, giant red caps, or aftermarket HEI conversions.
