Power Transistor
WARNING: This page is about a different car, the 1994 Mitsubishi Eclipse. However, it is still accessible from the selected car via links, so may be relevant.
- To test the section of the power transistor that controls cylinders No. 1 and 4 of the ignition coil, disconnect power transistor connector. Using a 1.5-volt dry cell battery, connect negative end of battery to terminal No. 3 of power transistor and positive end to terminal No. 7. See Fig 1 .
- Using an analog ohmmeter, check for continuity between terminals No. 3 and 8 of power transistor. Continuity should exist. With positive end of 1.5-volt battery disconnected, there should be no continuity. Replace power transistor if it fails test.
