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 becasue they may not generate enough spark to jump the wide gap.) Wt. 3 oz. Manufacturer: KD TOOLS Click here to visit the manufacturer's home page
