- Turn engine off. Ensure continuity exists between harness connector, ECU and power transistor. Check fusible link "G" (located in fusible link holder), ignition switch and continuity of ignition coil.
- Disconnect ignition coil and power transistor harness connector. With an ohmmeter, check continuity between terminals No. 2 and 1, terminals No. 2 and 3 and terminals No. 3 and 1. Continuity should exist between all these terminals. See Fig 1.
- If readings are not as specified, replace power transistor.
