A quick way to check no-start cars for ignition problems. Simply unplug the plug wire, connect it to the 7230, clamp the tester to a good engine ground, crank the engine, and watch for spark. A properly working electronic ignition system will be able to jump a spark across the tester’s spark gap (preset at .250"). Two 7230 testers are recommended for checking spark on DIS or EDIS applications—a good DIS or EDIS will fire two testers at once. By using two, you can check individual coil packs. (The 7230 may not work on point-type ignitions because they may not generate enough spark to jump the wide gap.)
