In automobile ignition system, the high-voltage ignition coil generates a high-voltage (10,000 volts or more), and the spark plug diverts it from high-tension ignition coil into the cylinder engine, spark between the spark plug electrodes will ignite the mixture. The detector could tell the good spark plugs from the bad by the strength of the spark.
