Lisle 19380 Spark Tester

When testing spark plugs, spark plug wires, and coils, you can do so without puncturing the wire. Simply place the grooved end of the tool over the plug wire while the engine is running, and the bulb will flash to indicate the presence of a spark.

The process is straightforward. With the engine running, position the grooved end of the test tool over the spark plug wire. This non-intrusive approach allows you to check the components without causing any damage to the wiring. As you hold the tool in place, the built-in bulb will flash, providing a visual confirmation that a spark is being generated.

This testing method is convenient and efficient. It eliminates the need to physically access the spark plugs or disconnect any wiring, which can be time-consuming and increase the risk of potential issues. By simply placing the tool over the plug wire, you can quickly assess the condition of the spark plugs, wires, and coils without disrupting the engine's operation.

The flashing bulb on the tool serves as a clear indicator of spark presence. If the bulb flashes, it confirms that the spark plug, wire, and coil are functioning properly and delivering the necessary ignition pulse to the engine. Conversely, if the bulb fails to flash, it suggests a problem with one or more of these components, requiring further investigation and potential replacement.

This non-invasive testing approach is particularly beneficial when working on vehicles with limited accessibility or tight engine compartments. Instead of having to remove and inspect each spark plug individually, you can quickly check the entire ignition system by simply accessing the plug wires. This saves time, effort, and minimizes the risk of accidentally damaging any delicate components during the testing process.

Furthermore, this testing method can be used on a variety of engine types, including gasoline and diesel engines. It is a versatile tool that can be employed in a wide range of automotive repair and maintenance scenarios, making it an essential item in any mechanic's toolbox.

In conclusion, the ability to test spark plugs, spark plug wires, and coils without puncturing the wire is a valuable capability that enhances the efficiency and effectiveness of automotive diagnostics and repair. By using this non-invasive testing approach, mechanics and DIY enthusiasts can quickly assess the health of the ignition system and identify any potential issues, ultimately ensuring the optimal performance and reliability of the engine.
