When it comes to wiring an ignition switch, it can be a bit overwhelming for those who are new to the field. However, the process is not complicated as it might seem at first glance. In this article, we will discuss the 3 wire ignition switch wiring diagram and provide all the necessary details to help you understand how to wire an ignition switch.
What is an Ignition Switch?
An ignition switch is a switch that is used to turn on and off the electrical system and motor of a vehicle. It is typically located on the dashboard of a car and is operated by a key. The ignition switch has three positions: off, on, and start. The off position turns off all electrical power to the vehicle, while the on position turns on the electrical power without starting the engine. The start position is used to engage the starter motor and start the engine.
The Three Wires of an Ignition Switch
An ignition switch has three wires that are connected to it. These wires are the battery wire, the accessory wire, and the starter wire. Each wire serves a different purpose in the electrical system of the vehicle.
The Battery Wire
The battery wire is the main power supply wire of the ignition switch. It is usually a thick red wire that is connected directly to the battery of the vehicle. The battery wire supplies power to the ignition switch and all other electrical components of the vehicle.
The Accessory Wire
The accessory wire is a thin red wire that is connected to the ignition switch. It is responsible for supplying power to the accessories of the vehicle, such as the radio, headlights, and other electrical components. When the ignition switch is turned to the accessory position, power is supplied to the accessories, but not to the motor of the vehicle.
The Starter Wire
The starter wire is a thick yellow wire that is connected to the ignition switch. It is responsible for supplying power to the starter motor of the vehicle. When the ignition switch is turned to the start position, power is supplied to the starter motor, which engages and starts the engine.
How to Wire an Ignition Switch
Wiring an ignition switch can be a bit tricky, but it is not difficult. Follow these steps to wire an ignition switch:
Step 1: Disconnect the Battery
The first step in wiring an ignition switch is to disconnect the battery of the vehicle. This will prevent any electrical shocks or damage to the vehicle.
Step 2: Locate the Ignition Switch
The next step is to locate the ignition switch in the vehicle. It is typically located on the dashboard of the vehicle, near the steering wheel.
Step 3: Identify the Wires
Identify the three wires of the ignition switch: the battery wire, the accessory wire, and the starter wire. The colors of the wires may vary depending on the make and model of the vehicle.
Step 4: Connect the Wires
Using pliers or a wire stripper, strip about half an inch of insulation from the ends of each wire. Connect the battery wire to the positive terminal of the battery, the accessory wire to the accessory terminal of the ignition switch, and the starter wire to the starter terminal of the ignition switch. Use electrical tape or wire connectors to secure the connections.
Step 5: Reconnect the Battery
Reconnect the battery of the vehicle and turn the ignition switch to the on position. Check to see if the electrical system and motor of the vehicle are functioning properly.
