When it comes to the heart of your 1965 VW Bug, the ignition coil plays a crucial role in sparking the engine to life. However, like any component, it can encounter glitches over time. If you suspect a faulty coil, it’s essential to test it promptly to ensure the smooth operation of your beloved classic. In this comprehensive guide, we will delve into the intricacies of testing the coil on your 1965 VW Bug, providing you with step-by-step instructions and valuable troubleshooting tips along the way.
To commence the testing procedure, you will require a multimeter, a fundamental tool for electrical diagnostics. Begin by setting the multimeter to the ohms setting and placing one probe on the positive terminal of the coil and the other probe on the negative terminal. A properly functioning coil should exhibit a resistance value within the range of 1.5 to 3 ohms. If the reading falls outside this range, it indicates a potential issue with the coil’s primary winding.
Next, we will move on to testing the coil’s secondary winding. This winding is responsible for generating the high voltage necessary to ignite the spark plugs. To test it, set the multimeter to the kilovolts (kV) setting and connect one probe to the center terminal of the coil and the other probe to the negative terminal. A healthy coil should produce a reading of around 20 to 30 kV. A significantly lower reading suggests a breakdown in the coil’s secondary winding, necessitating its replacement.
How To Test Coil On 1965 Vw Bug
If you’re having trouble starting your 1965 VW Bug, one of the possible causes could be a faulty coil. The coil is responsible for providing the spark that ignites the air/fuel mixture in the cylinders, so if it’s not working properly, your engine won’t be able to start. Here are a few steps on how to test the coil on your 1965 VW Bug:
- Disconnect the negative battery terminal.
- Locate the coil. It’s usually located on the side of the engine, near the distributor.
- Remove the two wires from the coil. One wire will be connected to the positive battery terminal, and the other wire will be connected to the distributor.
- Set your multimeter to the ohms setting.
- Touch one probe of the multimeter to the positive terminal on the coil, and touch the other probe to the negative terminal.
- The multimeter should read between 3 and 5 ohms. If it reads infinity, the coil is open and needs to be replaced.
- If the multimeter reads 0 ohms, the coil is shorted and needs to be replaced.
