1973-1974 Ford Point-Type Ignition System Circuit Diagram - Coil & Distributor

This document is a labeled schematic diagram of a typical conventional point-type ignition system circuit as used on 1973-1974 vehicles. The diagram illustrates the complete ignition circuit, distinguishing between the primary circuit (shown as a solid heavy line) and the secondary circuit (shown as a dashed line) via a legend. Components labeled in the diagram include the ignition switch (with IGNITION, START, and BATTERY terminal positions), a terminal connector, the primary resistance wire, a quick disconnect, the starter relay (marked with S and I terminals), the battery (with + and − terminals shown), the ignition coil, the distributor with cap and spark plug wires, and a spark plug. Grounds are indicated at the battery negative terminal and near the distributor. A reader can learn how the primary (low-voltage) side of a points ignition system routes power from the battery through the ignition switch, resistance wire, and relay to the coil, and how the secondary (high-voltage) side carries spark energy from the coil through the distributor cap to the spark plugs. The caption at the bottom, partially cropped, identifies it as a typical ignition system circuit used on conventional (1973-1974) point-type systems.
