Yellow/black – Starter motor activation
The yellow/black wire is responsible for activating the starter motor when the key is turned to the start position. This wire is connected directly to the starter motor and provides power to the motor when the switch is in the start position.
Light blue/red – Accessory power
The light blue/red wire is responsible for providing power to your vehicle’s accessories when the key is in the accessory or run positions. This wire is connected to a fuse in your vehicle’s fuse box and provides power to the accessories when the switch is in these positions.
Black/white – Backup power
The black/white wire is responsible for providing backup power to your vehicle’s electrical system. This wire is connected to a fuse in your vehicle’s fuse box and provides power to the electrical system if the battery is disconnected or dies.
Black – Ground
The black wire is responsible for providing a ground connection to your vehicle’s electrical system. This wire is grounded to the chassis of your vehicle and allows the electrical system to function properly.
Frequently asked questions
How do I test my ignition switch?
To test your ignition switch, you’ll need a multimeter. Start by disconnecting the wires from the back of the switch and turning the key to the on position. Use the multimeter to test each wire for voltage. The red/light green wire should have voltage in the accessory, run, and start positions. The yellow/black wire should have voltage in the start position. The light blue/red wire should have voltage in the accessory and run positions. If any of these wires don’t have voltage, the switch may be faulty and should be replaced.
How do I replace my ignition switch?
To replace your ignition switch, start by disconnecting the battery to prevent electrical shocks. Remove the steering column covers to access the switch. Disconnect the wires from the back of the switch and remove the switch from the steering column. Install the new switch and reconnect the wires. Reinstall the steering column covers and reconnect the battery.
What if my ignition switch still isn’t working after I replace it?
If your ignition switch still isn’t working after replacement, there may be other issues with your vehicle’s electrical system. Check the battery, starter motor, and fuses to ensure they’re functioning properly. If you’re still experiencing issues, it’s recommended to seek the assistance of a professional mechanic.
