The Lisle Coil-On-Plug Spark Tester, No. 20700, provides an easy way to check ignition systems with coil-on plugs. This tool offers the quickest way to test for no-start conditions, according to the company. High-visibility white lettering makes it easy to read the gap measurement from 0 to 40k, the round knob provides easy gap adjustment and the 12" ground wire comes with a shielded clip. Applications include Ford, Chrysler, Mitsubishi, Nissan and more. The standard plug wire tip can be unscrewed so the tester can be used on small engines and some motorcycles.
