Component Tests and General Diagnostics

NOTE: An analog-type Ohmmeter should be used.

1. Connect the negative (-) terminal of the 1.5V power supply to terminal 5 of the power transistor; then check whether there is continuity between terminal 5 and terminal 12 when terminal 6 and the positive (+) terminal are connected and disconnected.

NOTE: Connect the negative (-) probe of the circuit tester to terminal 12.




2. Replace the power transistor if there is a malfunction.
