Power Transistor Test

NOTE: The circuit tester used in the following test procedures should be of the "analog" type.
1. Disconnect the electrical connector to the Power Transistor.

Testing The Power Transistor:

2. Connect the positive lead of an ohmmeter to terminal # 2, and the negative lead of the ohmmeter to terminal # 3. There should be NO continuity.
3. Connect the positive lead of a 1.5 volt battery to terminal # 1 and the negative lead of the battery to terminal # 2. There should be continuity only while the battery is connected.
