Thexton Coil-On-Plug Spark Tester (458)

The Thexton Coil-On-Plug Spark Tester (458) is a specialized diagnostic tool engineered to troubleshoot ignition systems with coil-on-plug designs. This essential device helps automotive technicians and DIY mechanics quickly and accurately pinpoint the cause of no-start conditions or engine misfires. By connecting the tester directly to the coil and spark plug, you can visually inspect the spark, confirming if the ignition coil is functioning correctly. Its adjustable gap feature allows for a comprehensive evaluation of spark intensity, ensuring the coil is producing the required voltage to ignite the air-fuel mixture. The Thexton 458 is compatible with a wide range of vehicles, including models from Ford, Chrysler, Mitsubishi, and Nissan. Its simple yet effective design makes it a reliable addition to any toolbox, saving time and effort during automotive diagnostics. This tool simplifies a complex troubleshooting process, giving you a clear indication of a faulty ignition coil, which can help prevent costly and unnecessary part replacements.

KEY FEATURES AND BENEFITS:

• Adjustable Spark Gap: The tester features an adjustable gap from 0 to 40 kV. This allows you to not only check for the presence of a spark but also to evaluate its strength, providing a more detailed diagnosis of the ignition coil’s performance.
• Visual Confirmation: The design allows you to visually inspect the spark, which is a clear and immediate way to confirm if the ignition coil is firing. This eliminates the guesswork often associated with diagnosing misfires and no-start issues.
• Wide Vehicle Compatibility: The tool is designed to work on a variety of vehicles with coil-on-plug systems, including popular models from Ford, Chrysler, Mitsubishi, and Nissan, making it a versatile tool for a broad range of applications.
• Ground Wire Included: A 12-inch ground wire is integrated into the tool, ensuring a proper ground path for the spark. This simple feature guarantees the tool functions as intended, providing reliable and accurate results every time.

SPECIFICATIONS:

• Model: Thexton 458
• Included in Product: Thexton Coil-On-Plug Spark Tester and 12-inch ground wire

HOW TO USE:

1. Locate and Disconnect: Turn off the vehicle’s ignition. Locate the coil-on-plug for the cylinder you wish to test. Carefully disconnect the electrical connector from the ignition coil.
2. Remove the Coil: Remove the coil-on-plug from the spark plug.
3. Connect the Tester: Connect the boot of the coil-on-plug to one end of the Thexton 458 tester.
4. Attach to Spark Plug: Place the other end of the tester onto the top of the spark plug, ensuring a secure connection.
5. Ground the Tool: Connect the integrated 12-inch ground wire to a clean, unpainted metal surface on the engine block or chassis. This is a crucial step for the tool to function properly.
6. Test for Spark: Have a helper crank the engine or use a remote starter. Observe the tester’s gap. A visible, consistent spark indicates that the ignition coil is working. If there is no spark or a very weak one, the coil may be faulty.
7. Reconnect and Reassemble: After testing, remove the tester, re-install the coil, and reconnect the electrical connector.
