Spark Gap high voltage spark gap tester
High voltage spark gap tester is used in place of the spark plug when performing in cylinder pressure transducer testing. Also for ignition system testing.
The spark tester is used when performing an engine mechanics test using a cylinder pressure transducer. In this case, the plug wire of the cylinder under test is connected to the spark gap.
Please note that in cases where additional high-voltage equipment such as an adapter for plug wire extension or a spark tester is used, you should always carefully check the electrical connections in the high-voltage circuit and at the points of connection to the vehicle ground.
The spark tester uses a spark plug with an interference suppression resistor to suppress radio interference.
