Safety Information
Always observe the following safety precautions when using the Lisle 20610 Inline Spark Tester to prevent injury or damage to the vehicle.
- Personal Protective Equipment: Always wear appropriate personal protective equipment, including safety glasses, to protect against potential hazards from sparks or moving engine parts.
- Engine Off: Ensure the engine is completely off and cooled down before connecting or disconnecting the spark tester.
- Avoid Contact: Do not touch any live ignition components, including the spark tester, spark plug, or spark plug wires, while the engine is running or cranking. High voltage is present and can cause severe electrical shock.
- Moving Parts: Be aware of and avoid contact with moving engine parts (e.g., fan blades, belts) when the engine is running.
- Ventilation: Use the tool in a well-ventilated area to avoid inhaling exhaust fumes.
- Proper Connection: Ensure all connections are secure to prevent accidental disconnections during operation.
Product Overview
The Lisle 20610 Inline Spark Tester is designed for ease of use and durability. It features:
- Double-Ended Design: Equipped with both a straight boot and a 90-degree boot to accommodate various spark plug and wire configurations.
- Clear Housing: A transparent body allows for direct visual observation of the ignition spark.
- Simple Operation: Connects inline between the spark plug and the spark plug wire.
Setup
Before using the spark tester, ensure the vehicle's engine is turned off and cool. Locate the spark plug and its corresponding spark plug wire for the cylinder you wish to test.
- Identify the spark plug and its wire on the engine.
- Carefully disconnect the spark plug wire from the spark plug. Grasp the boot, not the wire, to avoid damage.
Operating Instructions
Follow these steps to test for spark using the Lisle 20610 Inline Spark Tester:
- Connect to Spark Plug: Attach one end of the Lisle 20610 Inline Spark Tester (choose the appropriate boot, straight or 90-degree) directly onto the spark plug terminal. Ensure a snug fit.
- Connect to Spark Plug Wire: Connect the disconnected spark plug wire to the other end of the spark tester. Again, ensure a secure connection.
- Start Engine: Have an assistant crank the engine or start it if safe to do so.
- Observe Spark: Look into the clear housing of the spark tester. A flashing light inside the tester indicates the presence of an ignition spark. The color of the spark may vary (often orange/red).

After testing, turn off the engine, carefully disconnect the spark tester, and reattach the spark plug wire to the spark plug.
Maintenance
The Lisle 20610 Inline Spark Tester requires minimal maintenance to ensure its longevity and accurate performance.
- Cleaning: Wipe the tool with a clean, dry cloth after each use to remove any dirt, oil, or moisture. Do not use harsh chemicals or solvents.
- Storage: Store the spark tester in a clean, dry place, away from extreme temperatures and direct sunlight.
- Inspection: Before each use, visually inspect the tester for any signs of damage, such as cracked housing, frayed wires, or loose connections. Do not use a damaged tester.
Troubleshooting
If you do not observe a spark when using the Lisle 20610 Inline Spark Tester, consider the following:
- No Spark Indication: If the tester does not flash, it indicates a lack of spark from the ignition system.
- Check Connections: Ensure the spark tester is securely connected to both the spark plug and the spark plug wire. A loose connection can prevent proper operation.
- Engine Cranking: Verify that the engine is cranking properly. The tester will only show spark if the engine is attempting to ignite.
- System Diagnosis: If no spark is detected, the issue lies within the vehicle's ignition system (e.g., faulty spark plug, bad spark plug wire, ignition coil, distributor, or other related components). The spark tester confirms the absence of spark, guiding further diagnosis.
- Tester Integrity: While rare, ensure the tester itself is not faulty. If possible, test it on a known working ignition system to confirm its functionality.
