The correct answer among the choices given is option B. The length of the metal threads at the end of a spark plug is called the insulator. The insulator is the main part of a spark plug and is typically made from alumina. This is a very hard ceramic material with high dielectric strength.
You're here because you got a No spark result from two spark plug wires that DO NOT feed spark to Paired Cylinders. The next step is to test for spark directly on the the ignition coil pack towers that feed those two spark plug wires (that did not fire off spark in TEST 1). You'll test one coil tower at a time.1  Remove the spark plug wire that did not fire off spark from the ignition coil pack. This is the wire that feeds the Switching Signal to the individual ignition coil that fires cylinders 3 and 4. 2  Attach the probe-end of your Test Light to that tool. 3  Remember, this test must be performed with the Ford coil pack connected to its connector.
