1. With a voltmeter check connector No.1 terminal A for voltage when the ignition switch is ON or START position. If there is no voltage check wiring and connectors between Ignition Control Module (ICM) and ignition switch.
2. Disconnect connector No.1 on the Ignition Control Module and check terminal B to insure that there is a good ground, if not, repair as needed.
3. With a test light check connector No.2 terminal B for a flashing light when the engine is being cranked. If the test light flashes and there is still no secondary spark output replace the Ignition Control Module (ICM). If test light does not flash go to TEST 11.
