TO USE: with engine off, remove rubber boot from spark plug, & Simply connect the tester between the spark plug and the plug wire, if ignition spark is being sent to the cylinder, light in tester glows & mirrors the spark. Testers light up and/or buzz to indicate testing result. Brightness of the light indicates the quantity of the spark. The pulses should be bright and consistent. Make sure your wires have a good connection. If the connection is good and the pulse doesn't change. Suspect a bad ignition coil. TIP: If you're testing in bright lighting conditions and not getting the right result, try again in a less bright environment.
