Introduction
The ignition switch is an essential component of a vehicle’s electrical system. It acts as a starter, enabling the vehicle to start and run. A four-position ignition switch is a type of switch that has four different positions: off, accessory, on, and start. In this article, we will discuss the wiring diagram for a four-position ignition switch.
Wiring Diagram
Before we delve into the wiring diagram, we need to understand the four positions of the ignition switch:
| Position | Description |
|---|---|
| Off | The switch is in the off position, and the engine is not running. |
| Accessory | The switch is in the accessory position, and the electrical systems of the vehicle are active without the engine running. |
| On | The switch is in the on position, and the electrical systems are active with the engine running. |
| Start | The switch is in the start position, and the engine is starting. |
The wiring diagram for a four-position ignition switch is relatively simple. It consists of four wires:
- Red wire: This wire is connected to the battery’s positive terminal and provides power to the switch.
- Black wire: This wire is connected to the battery’s negative terminal and is used as a ground for the switch.
- Yellow wire: This wire is connected to the ignition module and provides power to the accessory position of the switch.
- Pink wire: This wire is connected to the starter solenoid and provides power to the start position of the switch.
