Dual Hole Spark Plug Tester Ignition Measurement Tool Car Spark Plug Tester Glow Plug Analyzer Diagnostic Tool

Car Spark Plug Test Principle: In a car ignition system, a high voltage ignition coil produces a high voltage (10000 volts or more) and a spark plug diverts it. A high pressure ignition coil is formed in the cylinder engine, and sparks between the spark plug electrodes ignite the mixture. Detector You can distinguish between good and bad spark plugs by the intensity of the spark. Car Spark Plug Tester User Manual: 1. Place the spark plug in hole 1 or 2 of the tester. If you want to compare the new spark plug with the old spark plug, Place the new spark plug in hole 1 and the old spark plug in hole 2. 2. Connect to power supply 3.
