If you own a 1966 VW Bug, it’s important to regularly check and maintain its ignition switch. This component is responsible for controlling the electrical current that powers your vehicle’s engine, and if it’s not working properly, your car won’t be able to start. Ignition switch issues are one of the most common problems faced by vintage VW Bug owners. In this article, we’ll guide you through the steps on how to check the ignition switch on your 1966 VW Bug to ensure it’s functioning correctly.
Before we jump into the steps, it’s important to note that if you’re not confident in your ability to check the ignition switch, it’s best to seek help from a professional mechanic. Electrical components can be tricky to diagnose, and it’s always better to be safe than sorry.
Step 1: Gather Your Tools
To check the ignition switch, you’ll need:
- Socket wrench
- Screwdriver
- Wire brush
- Multimeter
- Clean cloth
Step 2: Locate the Ignition Switch
The ignition switch of a 1966 VW Bug is located behind the ignition lock cylinder. To access it, you’ll need to first remove the steering wheel by unscrewing the center bolt. Then, carefully remove the steering column cover to expose the ignition switch.
Step 3: Inspect the Wires
Before testing the ignition switch, it’s essential to check the wires connected to it. Ensure they are clean and free of rust or corrosion. If you notice any grime buildup, use a wire brush to clean the wires.
Step 4: Test the Ignition Switch
Using a multimeter, set it to the “ohms” function. Touch one of the multimeter probes to the center terminal of the ignition switch and the other to the base of the switch. If the multimeter reads a low resistance, there is a short in the switch, and it will need to be replaced.
Next, test the continuity of the switch. Touch one of the multimeter probes to the center terminal and the other to each of the other two terminals. If the switch is working correctly, there should be no continuity between the center terminal and the other two.
Step 5: Test the Lock Cylinder
If the ignition switch is functioning correctly, the issue may lie in the lock cylinder. Insert the key into the cylinder and turn it. If the key doesn’t turn smoothly, the lock cylinder may be worn out, and it will need to be replaced.
