Power Transistor

WARNING: This page is about a different car, the 1994 Mitsubishi Diamante. However, it is still accessible from the selected car via links, so may be relevant.
  1. Disconnect power transistor connector. Using a 1.5-volt dry cell battery, connect negative end of 1.5-volt battery to terminal No. 2 of power transistor and positive end to terminal No. 1. See Fig 1 .
  2. Using an analog ohmmeter, check for continuity between terminals No. 2 and 3 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.
