Start is only hot 12v dc during cranking and run is hot 12v dc from the moment you turn the key on through crank and after crank. Disconnect purple lead at back of alternator.

Ignition coil ballast resistor wiring diagram welcome to my internet site this blog post will certainly discuss concerning ignition coil ballast resistor wiring diagram. In the years when engines were a lot easier to work with a ballast resistor was used in order to prolong the life of the coil. As a matter of fact a bad diode trio in a conventional alternator can do the same damage. 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.

Strip the end of the positive wire from the ignition and connect it to the positive end of the resistor. Ohmmeter test procedure resistor wire disconnect 20 gauge purple red resistor wire from ignition coil positive terminal. Here is a picture gallery about ignition coil ballast resistor wiring diagram complete with the description of the image please find the image you need. The purpose of an ignition ballast resistor between the ignition switch 12v and the ignition coil positive terminal is to restrict current flow.

Connect ohmmeter between purple red wire at coil and purple wire at alternator. Set the ballast resistor up to the firewall and screw the clamps in place. Pat conners wrote that wires 2 and 3 should go where 4 and 5 are and vice versa. All special tools required.

Resistor wire for models. 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. From the other terminal on the resistor a wire goes to the positive on the coil. Meter low ohms scale should read.
