An LED circuit tester for measuring voltage and spark plug leads that is simple and easy to use.
This tester is useful for continuity testing, 3-12v DC voltage testing, 9v-12v battery testing, spark plug ignition voltage testing and live wire testing. Complete with light indicators to show results.
Identifying Live Wires
DC Voltage Testing (3v-12v)
12V Vehicle Battery Testing
9v Vehicle Battery Testing
Repeat procedure for 12v
EXTREME CAUTION: This test involves working around high voltage. Check Plug wire insulation. Avoid direct body contact with spark plug wires as insulation failure may result in shock. Through the tester, faulty insulation will only result in an unpleasant sensation.
Spark Plug Ignition Voltage Test
High Voltage - indicated with flicker in the Spark Plug HT indicator. No illumination will indicate shorted plug, open circuit lead or other ignition fault. NOTE: The test can be repeated at higher rpm to increase intensity of LED.
WARNING: NOT suitable for 240 volt AC voltage.
It is important to read the enclosed instruction before use.
