Testing A Points Condenser Made Easy

Testing a points condenser is a crucial step in troubleshooting and maintaining your classic car's ignition system. The points condenser, also known as a capacitor, plays a vital role in ensuring the proper functioning of the ignition system. In this article, we will guide you through the process of testing a points condenser, making it easy for you to diagnose and repair any issues.

Understanding the Points Condenser

Before we dive into the testing process, it's essential to understand the basics of the points condenser. The points condenser is a capacitor that stores electrical energy and releases it to the ignition coil, allowing the spark plugs to fire. A faulty points condenser can cause a range of issues, including misfires, rough idling, and decreased engine performance.

Why Test the Points Condenser?

Testing the points condenser is a straightforward process that can help you identify any issues with the ignition system. By testing the condenser, you can determine if it's functioning correctly or if it needs to be replaced. This can save you time and money in the long run by preventing more severe problems from developing.

Tools and Materials Needed

To test the points condenser, you'll need the following tools and materials:

• A multimeter
• A spark tester
• A points condenser tester (optional)
• A replacement points condenser (if necessary)

Step-by-Step Testing Process

Follow these steps to test the points condenser:

1. Locate the points condenser: The points condenser is usually located near the ignition coil or distributor cap.
2. Disconnect the battery: Make sure the battery is disconnected to prevent any accidental starts or electrical shocks.
3. Remove the distributor cap: Take off the distributor cap to access the points condenser.
4. Identify the points condenser: Look for the points condenser, which is usually a small, cylindrical component with two terminals.
5. Set the multimeter: Set the multimeter to the capacitance function (usually denoted by a capacitor symbol).
6. Connect the multimeter: Connect the multimeter leads to the points condenser terminals.
7. Take a reading: Take a reading on the multimeter to determine the capacitance value.
8. Compare the reading: Compare the reading to the manufacturer's specifications or a known good value.
9. Test the spark: Use a spark tester to test the spark output.
10. Replace the points condenser (if necessary): If the points condenser is faulty, replace it with a new one.

Interpreting the Results

Once you've completed the testing process, you'll need to interpret the results. Here's what you can expect:

• A good points condenser will show a capacitance value within the manufacturer's specifications.
• A faulty points condenser will show a lower or higher capacitance value than expected.
• If the spark tester shows a weak or no spark, it may indicate a faulty points condenser.

Troubleshooting Tips

Here are some troubleshooting tips to keep in mind:

• Make sure the points condenser is properly connected to the ignition coil and distributor cap.
• Check for any signs of wear or damage on the points condenser terminals.
• If you're using a points condenser tester, follow the manufacturer's instructions for proper use.
