The power transistor is located between the ignition coil and the distributor on 1993-98 3.0L engine models. On 1999-00 3.3L engine models, the power transistor is located inside of the distributor, and cannot be replaced separately.
Removal & Installation
The power transistor is part of the distributor assembly, and must be replaced as a unit. Please refer to Distributor, Removal and Installation for the procedure.
The use of a digital volt ohmmeter (DVOM) is required for the following power transistor tests. If using a DVOM with a diode or transistor test function, follow the meter manufacturer-s instructions for testing transistors.
- Disconnect the negative battery cable.
- Disconnect the two-wire ignition coil harness connector from the distributor electrical connector.
- Disconnect the six-wire distributor harness connector from the distributor.
Connect the digital ohmmeter leads to pin 2 of the six-pin distributor terminal, and to the green wire (pin 2) terminal of the two-wire distributor electrical connector. If the resistance is 0 ohms, replace the distributor.
