From there, the high voltage travels down the distributor cap to the rotor and out to the spark plugs via the spark plug wires, following the firing order of 1-8-4-3-6-5-7-2. Begin at the battery and locate the main power feed.

Troubleshooting Common Ignition Issues When diagnosing starting or running problems, the wiring diagram is an invaluable tool for isolating the fault. For HEI distributors, the module is contained within the distributor cap, simplifying the external wiring.
This module handles the switching of current to the primary windings of the coil, replacing the mechanical breaker points. This action induces the high voltage in the secondary winding, which is then sent to the rotor and out through the spark plug wires.
