What is a 6 Terminal Ignition Switch?
A 6 terminal ignition switch is a type of ignition switch that has six electrical terminals or connectors. These connectors are used to connect the ignition switch to various components of the vehicle, such as the starter motor, battery, and other electrical components.
The six terminals or contacts are usually numbered, and different wires are connected to each of them. The terminals are either male or female, and they can be round or flat.
Terminal Numbers and Uses
The following table shows the terminal numbers and their uses:
| Terminal Number | Use/Connection |
|---|---|
| 1 | Connects to the starter motor solenoid. |
| 2 | Connects to the battery or main power source. |
| 3 | Connects to the ignition coil or module. |
| 4 | Connects to the accessory circuit. |
| 5 | Connects to the starter motor solenoid. |
| 6 | Connects to the ground or negative battery terminal. |
Wiring a 6 Terminal Ignition Switch: Step by Step Guide
Step 1: Disconnect the Battery
The first step is to disconnect the battery to prevent any electrical shock or damage to the vehicle. Remove the negative cable from the battery terminal and secure it to avoid any accidental contact.
Step 2: Identify the Wires and Terminals
Identify the wires you will need to connect to the ignition switch and the terminals you will use. The wires can be distinguished by their color codes, and the terminals by their numbers or markings.
Step 3: Connect the Battery Cable to Terminal 2
Connect the battery cable to terminal 2 of the ignition switch. This terminal provides power to the switch and the electrical components of the vehicle. Use a wrench or pliers to tighten the connection securely.
Step 4: Connect the Starter Solenoid Wires to Terminals 1 and 5
Connect the wires from the starter solenoid to terminals 1 and 5 of the ignition switch. These terminals activate the starter motor, and they are usually connected with heavy gauge wires. Use a wrench or pliers to tighten the connections securely.
Step 5: Connect the Ignition Coil or Module Wire to Terminal 3
Connect the wire from the ignition coil or module to terminal 3 of the ignition switch. This terminal provides power to the ignition system, and it is usually connected with a medium gauge wire. Use a wrench or pliers to tighten the connection securely.
Step 6: Connect the Accessory Circuit Wire to Terminal 4
Connect the wire from the accessory circuit to terminal 4 of the ignition switch. This terminal provides power to the accessory circuits of the vehicle, such as the radio, lights, and air conditioning. Use a wrench or pliers to tighten the connection securely.
Step 7: Connect the Ground Wire to Terminal 6
Connect the ground wire or negative battery cable to terminal 6 of the ignition switch. This terminal provides the ground connection for the switch and the electrical system of the vehicle. Use a wrench or pliers to tighten the connection securely.
