Hei distributor wiring diagram ballast resistor. Gm hei electronic distributor how to wire and run install. Remember on a points style distributor an inline ballast resistor or resistance wire decreases the voltage from the battery to around 9 5 volts when running. This feed wire must be 12 gauge from the ignition switch to the bulkhead and then from the bulkhead to the hei power terminal. If a resistance wire is present.
That s a fine tutorial on how to install a mopar electronic ignition box but a gm hei module creates a hotter spark and doesn t use a ballast resistor. Get a standard chrysler electronic ignition distributor wrecking yard auto show etc. The way i do it. Each part should be set and connected with different parts in specific manner.
I would power the new hei system through a relay. The purpose of an ignition ballast resistor between the ignition switch 12v and the ignition coil positive terminal is to restrict current flow through the ignition coil. If converting from a point type ignition remove any resistance wire or ballast resistor that may have been previously used. The relay would be energized by the blue wire on the ballast resistor and one side of the relay would go to the alternator output stud through a fuse.
How the ballast resistor works. Replace the wire with a 12 gauge copper stranded wire. Also you will need to move the distributor pick up wire between systems. Points style distributors do use 12.
Failure to use an ignition ballast resistor will eventually destroy the ignition module. The other side of the relay would go to the new hei system. If not the arrangement will not function as it ought to be. When using hei the distributor requires a 12 volt feed.
