Chrysler ballast resistor wiring diagram. The ballast resistor should be mounted in a solid location either near the ecu or on the firewall. Step 12 ballast resistor installation. The typical automotive ignition system prior to 1974 consisted of a coil and ballast resistor with breaker points to interrupt the current flow when a spark was needed. Installing the mopar electronic ignition requires a distributor with the magnetic pickup and one more wire to the ballast resistor.

Dodge ignition wiring duration. Chrysler master tech 1972 volume 72 3 ignition systems for 72 duration. Connect one side of the ballast resistor to the positive side of the coil. Some brands utilized a resistor in the coil or a resistor wire hidden in the wiring from the ignition switch but mopar put their resistor or ballast resistor on the firewall or inner fender.

1973 master technician service conference chrysler plymouth dodge imperial mr. Ok i have a 59 chrysler new yorker that i switched to electronic ignition and they had me get the orange box and ballast resister so i wired it up like the diagram but my question is the one side of the ballast that goes to the coil has the ignition start wire ran to it. When checking voltage at the battery i got 12 43 volts. Your input on these numbers appreciated.

When i turn the ignition switch on i get 10 55 volts at input wire disconnected from resistor to the ballast resistor. This simple system is easy for even the novice mechanic to wire. Depending on the type of installation there are two methods for ballast resistor wiring. I would like a 4 pin dodge chrysler ignition ecu box from a 1983 pickup truck example dodge d 150 with 318 v8 and the 2 pin ballast resistor that goes with it.

With the wires connected to the resistor and the ignition switch on i get 4 75 volts at the positive side of the coil. This video explains how the ballast resistor works. I would like a 5 pin dodge chrysler ignition ecu box from a 1975 pickup truck example dodge w 100 with 318 v8 and the 4 pin ballast resistor that goes with it. The job of the ballast resistor was to inhibit current to a level that would not overheat the coil.
