1971 Dodge Ignition Switch Wiring Diagram: A Comprehensive Guide

If you own a 1971 Dodge vehicle, understanding the ignition switch wiring diagram is crucial for proper maintenance and troubleshooting. This article will provide you with a comprehensive guide to the 1971 Dodge ignition switch wiring diagram.

What is the Ignition Switch?

The ignition switch is an electrical switch that is activated by the key when inserted into the ignition lock cylinder. This switch is responsible for sending power to various electrical components, including the starter motor, fuel pump, and ignition coil.

The ignition switch also controls the operation of the accessory circuits, including the radio and interior lights. Understanding the wiring diagram of the ignition switch is necessary for proper diagnosis and repair of any electrical issues.

The Basic Components of the Ignition System

The ignition system in a 1971 Dodge vehicle consists of several components, including the battery, wiring harness, ignition switch, starter relay, ignition coil, distributor, and spark plugs.

When the key is turned in the ignition switch, a signal is sent to the starter relay, which then sends power to the starter motor. The starter motor then cranks the engine, allowing it to start. At the same time, power is sent to the ignition coil, which produces a high voltage spark that ignites the fuel mixture in the engine.
