Thexton Ignition Spark Tester (404) (Model THE404)
The Thexton Ignition Spark Tester (404) is a professional-grade diagnostic tool engineered to help mechanics and DIY enthusiasts quickly and accurately troubleshoot ignition system problems. When a vehicle or engine fails to start, this tool is the first line of defense in determining if the issue is related to a lack of spark. It provides a reliable method for testing the ignition coil's ability to generate a powerful spark under conditions that simulate a running engine. Its adjustable gap feature is what sets it apart, allowing you to test the coil's voltage output against a specific resistance, thereby providing a more thorough and reliable diagnosis than a simple open-air spark test. The tool is designed to work across a broad range of ignition systems, from modern, high-energy electronic systems found in cars to the simpler systems in small engines, making it an indispensable part of any diagnostic toolkit.
KEY FEATURES AND BENEFITS:
Adjustable Spark Gap: Simulates the high-pressure environment of a running engine for accurate diagnosis.
Versatility: Suitable for high-energy automotive ignition coils as well as small engines like lawnmowers, chainsaws, and motorcycles.
Clear Visibility: Integrated gauge with high-visibility background allows spark observation even in low light.
Safety Shield: Protects the user from sparks and electrical shock during testing.
Quick Feedback: Provides immediate spark confirmation to streamline troubleshooting.
Adjustable Gap: 0 to 40,000 volts
Included in Product: Thexton Ignition Spark Tester (404) with attached ground clip
Prepare the engine: Ensure the engine is off and cool before starting. Locate the spark plug boot to be tested.
Connect the tester: Remove the spark plug boot from the spark plug and insert the metal tip of the tester into the boot.
Ground the tool: Attach the tester’s alligator clip to a clean, unpainted metal surface on the engine block.
Crank the engine: Have a helper crank the engine briefly while you observe the tester.
Observe the spark: Watch the adjustable gap for a spark. Adjust the gap to measure coil strength and performance.
