4. Operating Instructions

The ANCEL SP20 Spark Plug Tester is designed for one-touch operation, making spark plug diagnosis quick and efficient.

4.1 Single Spark Plug Test

1. Ensure the tester is powered on and the protective cover is securely in place.
2. Insert one spark plug into either test hole.
3. Press the start button. The tester will begin simulating ignition conditions (approximately 2000 RPM) and generate sparks.
4. Observe the spark. A strong, consistent blue spark indicates a healthy spark plug.

4.2 Dual Spark Plug Comparison Test

This feature allows for direct comparison between two spark plugs, such as a new one versus an old one, or two used plugs from different cylinders.

1. Ensure the tester is powered on and the protective cover is securely in place.
2. Insert two spark plugs into both test holes.
3. Press the start button. The tester will simultaneously generate sparks for both plugs.
4. Compare the intensity and consistency of the sparks from both plugs. A noticeable difference in spark strength or color can indicate a faulty plug.

5. Maintenance

To ensure the longevity and optimal performance of your ANCEL SP20 Spark Plug Tester, follow these simple maintenance guidelines:

• Cleaning: After each use, wipe the tester with a soft, dry cloth to remove any dust or debris. Do not use abrasive cleaners or solvents.
• Storage: Store the tester in a cool, dry place away from direct sunlight and extreme temperatures. Keep it in its original packaging or a protective case when not in use.
• Protective Cover: Regularly inspect the protective cover for any cracks or damage. Replace it if necessary to maintain safety during operation.

6. Troubleshooting

If you encounter issues with your ANCEL SP20 Spark Plug Tester, please refer to the following common problems and solutions:

6.1 No Spark or Weak Spark

• Power Supply: Ensure the tester is connected to a stable 110-120V power supply.
• Protective Cover: Verify that the protective cover is fully and correctly seated. The tester will not operate without it for safety reasons.
• Spark Plug Condition: The spark plug itself might be faulty. Try testing with a known good spark plug.
• Spark Plug Length: Important Note: This spark plug tester is not compatible with very short spark plugs. Due to the plug length, the contacts may not reach the bottom of the testing port. If you suspect this is the issue, please contact support.

6.2 Device Not Turning On

• Power Connection: Check if the power adapter is securely plugged into both the tester and the wall outlet.
• Outlet Functionality: Test the power outlet with another device to ensure it is working correctly.
• Power Adapter: Inspect the power adapter for any visible damage.

If these troubleshooting steps do not resolve the issue, please contact ANCEL customer support for further assistance.
