Dual-Port Spark Plug Ignition Tester – High Voltage Coil Diagnostic Tool

Product overview

This dual-port spark plug ignition tester is a handy diagnostic tool for checking whether ignition coils and spark plug leads are delivering a high-voltage spark. It is designed for general automotive use rather than a specific vehicle, making it a useful addition to a home garage or workshop toolbox when chasing misfires and no-start faults.

Rather than swapping parts on guesswork, a spark tester lets you see whether a cylinder is receiving ignition, which can save both time and money when tracking down an engine fault. It is equally useful for mechanics and enthusiasts maintaining older vehicles.

Vehicle compatibility

The listing describes this tool as universal and not tied to any particular make or model. It is intended for use on petrol engines with conventional spark ignition. Always confirm that the tester is suitable for your ignition system type, particularly on vehicles with high-energy or coil-on-plug systems, by checking the instructions supplied with the tool.

Key features

• Dual-port design for testing ignition output
• Helps isolate weak coils or leads quickly
• Universal application across vehicle brands

Technical specifications

Installation requirements

Use the tester only with the engine and ignition in a safe state as described in its instructions. Keep hands, tools and loose clothing clear of high-voltage components and moving engine parts while cranking. Disable fuel delivery if needed to prevent flooding during repeated cranking tests. If you are unsure how to test ignition safely, seek help from a qualified technician, as ignition systems can deliver a dangerous shock.
