Power Transistor
CAUTION:
Power transistor test must be performed in less than 10 seconds to prevent coil from burning and power transistor from breaking.
- Power transistor is located in distributor. Disconnect distributor connector. Using a 1.5-volt dry cell battery, connect negative end of 1.5-volt battery to distributor assembly connector terminal No. 4 and positive end to distributor assembly connector terminal No. 3. See Figure.
- On Diamante, check for continuity between distributor assembly connector terminals No. 1 and 4. On Eclipse 3.0L, Eclipse Spyder 3.0L, Galant 3.0L and Mirage 1.5L, check for continuity between distributor assembly terminals No. 2 and 4. Continuity should exist. With positive end of 1.5-volt battery disconnected, there should be no continuity. Replace power transistor if it fails test.
