Mallory coil 29216 and 29219
HI,
i have a 1965 283 canadian Pontiac Parisienne. Problem: I have install a crane cams XR-i electronic ignition module and replaced my stock GM ignition coil with the MALLORY electronic coil 29216 and use a extern ballast resistor. Runs great. Cool. My questions: -Does i need the ballast resistor or can the system work without the ballast resistor? -is it better to use the Mallory coil 29219? Have seen that the 29216 is only for Chrysler??? What is a capacitive discharge ignition system? Has my car this system or not, because that one of the differences in the Mallory coil 29216 and 29219. Which coil i should use? Many thanks & Greetings from Germany |
Hello. The Crane cams website shows the XR-i system is used with an external resistor. On most GM cars, the resistance is actually a resistive wire in the wire harness and should still be present if the wires have not been modified.
You must keep the resistance to use the XR-i. A capacitive discharge ignition is usually an aftermarket ignition such as a MSD-6AL. Most standard ignitions are NOT capacitor discharge, although some GM models in the 1960's had CD systems as a high-performance option. CD systems use a different coil and do not use an external resistor. For your application, use the existing resistor wire and a replacement-style coil, not a coil for CD applications. George |
