Ignition with ballast resistor wiring diagram. Set the ballast resistor up to the firewall and screw the clamps in place. Ohmmeter test procedure resistor wire disconnect 20 gauge purple red resistor wire from ignition coil positive terminal. As a matter of fact a bad diode trio in a conventional alternator can do the same damage. The job of the ballast resistor was to inhibit current to a level that would not overheat the coil.

The following diagram shows the 5 pin box with dual ballast resistor. This simple system is easy for even the novice mechanic to wire. How to install a pertronix ignitor ignition system classic car episode 280 autorestomod duration. Autorestomod manic mechanic gasoline media 214 019 views 17 19.

Disconnect purple lead at back of alternator. From the other terminal on the resistor a wire goes to the positive on the coil. Strip the end of the positive wire from the ignition and connect it to the positive end of the resistor. All special tools required.

Connect wires to positive. 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. Ignition coil ballast resistor wiring diagram welcome to my internet site this blog post will certainly discuss concerning ignition coil ballast resistor wiring diagram. 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.

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. The purpose of an ignition ballast resistor between the ignition switch 12v and the ignition coil positive terminal is to restrict current flow. 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. Meter low ohms scale should read.

Connect ohmmeter between purple red wire at coil and purple wire at alternator. Ignition coil ballast resistor wiring diagram with ignition coil ballast resistor wiring diagram image size 609 x 360 px and to view image details please click the image.
