Description

The Lisle 50850 is a handheld ignition spark tester designed for quickly diagnosing ignition issues. It checks for spark at the plug wire without requiring the removal of the spark plug. This tool is calibrated to accurately measure ignition voltage and works with both standard and electronic ignition systems. It features a visual indicator light and requires no external power source, operating on hand power alone. The tester is built for durability and reliability, making it suitable for professional mechanics and DIY enthusiasts alike. To use, simply adjust the calibration screw, attach the spark plug wire, ground the tester to the engine, and crank the engine to observe the indicator light for spark activity.
