As engine technology changes, so does the need for ignition systems and a way to test them. MSD's Universal Ignition Tester can test not only traditional single-coil ignition systems but also coil-per-cylinder applications. The 89981 also lets you create an rpm run and let the tester sweep through the rpm range, so you can watch the ignition activate accessories such as shifters and nitrous solenoids.
