Power Transistor
COMPONENT TESTNOTE: An analog-type ohmmeter should be used.
1. Connect the negative (-) terminal of the 3.0 volt power supply to terminal 2 of the power transistor; then check whether there is continuity between terminal #3 and terminal #1 when terminal #1 and the positive (+) terminal of the 3.0 volt power supply is connected and disconnected.
NOTE: Connect the negative (-) terminal of the ohmmeter to terminal #5.
