Car Spark Plug Tester Detector with Two Test Holes. In an automobile ignition system, the high-voltage ignition coil generates high voltage (10000 volts or more) and the spark plug diverts it from the high-voltage ignition coil into the engine cylinder. A spark between the electrodes of the spark plug ignites the mixture. . The detector could distinguish good spark plugs from bad ones by the strength of the spark. Features: Car Spark Plug Tester Detector with Two Test Holes. Can be used to test the performance of spark plugs and their ignition resistance. Applies to 12V gasoline vehicle spark plugs. At the same time you can test two spark plugs and if you suspect that one plug is not working properly you can compare and test to make a judgment. Is to work and fast testing. How to use: 1.
