Master Automotive Secondary Ignition Diagnostics

Troubleshooting modern automotive ignition systems can be challenging due to highly compact engine designs. The Hantek HT308 Coil-on-Plug Extension Cord is the ultimate diagnostic accessory designed to solve this exact problem. By safely bridging the gap between the ignition coil and the spark plug, this tool allows mechanics to capture precise secondary ignition waveforms with unparalleled accuracy. Modern vehicles frequently utilize Coil-on-Plug (COP) systems where the ignition coil sits directly on top of the spark plug. While this design improves engine efficiency, it removes the traditional high-tension leads, making secondary ignition measurements nearly impossible without specialized equipment.

By using a high-quality extension cord, you safely extend the high-voltage connection. This gives your pickup probe a clear, accessible point to clip onto. It ensures you get a clean, readable signal on your screen, allowing you to easily identify engine misfires, coil degradation, or spark plug fouling. Don’t let hidden ignition coils slow down your repair times. Equip your garage with the right tools to diagnose misfires efficiently and accurately on the first try.
