Spark Plug Pick Up / Probe, Reduced 25%. For Automotive Troubleshooting

KV Spark Plug Probe for professional garage and automotive mechanics. Clamps around standard spark plug wiring Probe cord is 56” long. No book or manual included. Condition is (lightly) Used. Shipped USPS 1st class Exercise caution. The vehicle should not be running when clamping or removing the probe, in order to avoid getting caught on moving part. For experienced mechanics only. This probe steps down the spark plug’s high voltage so that it can be measured on a hand held voltmeter (or waveform looked at on an oscilloscope) No need to remove the spark plug wire. To use, clamp around the spark plug wires and plug the male ends into a compatible voltmeter. Set voltmeter with on AC, and anywhere from 10-20v range. (200V range is ok, but you will loose some resolution). The easiest way to trouble shoot the ignition system is to compare the spark plug voltage on each cylinder and make sure they are approx the same. Output voltage from the probe will be approximately 2-3 volts, depending on your vehicles ignition coil output, rpm, etc. and your meter’s input impedance. For more advanced users, the probe output could be connected to an oscilloscope in order to compare the waveform. Keywords: diagnostic engine ignition automotive spark troubleshoot
