Hei Distributor Cap Wiring Diagram. That distributor is an easy one. This wiring pigtail features a dual HEI connector that helps clean up your engine bay by eliminating the use of single spade Learn about the wiring of GM HEI Ignition Distributors with our diagrams and guide.
An HEI distributor that has a worn pick-up coil or corroded magnetic poles will produce a weak spark, with insufficient voltage to ignite the combustion gases.
I'm not sure about the wiring harness from Crane Cams.
The HEI distributor is still an inductive-discharge ignition, but exchanges points for an electronic device called a module. Since this system produces more voltage and amperage output than a point-type ignition, it requires a larger-diameter cap Actually most HEI systems run well with spiral-core wires. It's no problem to rebuild the connection, I go to a juck yard and find one that is still in tact and draw a diagram from it. good luck.
