Ignition Cable: Description and Operation

Ignition Wire:

PURPOSE
The coil wire connects the ignition coil to the distributor cap, allowing high voltage to flow from the coil to the distributor cap.

The spark plug wires connect the terminals on the distributor cap to the spark plugs, allowing high voltage to flow to the spark plugs.

OPERATION
Provides a path for the current to flow from the coil to the distributor cap, and from the distributor cap to the spark plugs. The spark plug will then fire the air/fuel mixture.

CONSTRUCTION
The ignition wires have an internal resistance to suppress radio static and to eliminate static that may interfere with sensitive computer components.
