② Attach black connector to spark plug
③ Insert metal end of tester into spark plug wire

TIP
» If ignition spark is being sent to the cylinder, light in tester glows & mirrors the spark.
» Brightness of the light indicates the quantity of the spark. Pulse and brightness are correlated
» If the wire connection is good and the pulse does not change, the ignition coil is broken
