Power Transistor
- Connect analog ohmmeter leads between power transistor terminals No. 3 and No. 7. Ohmmeter should indicate no continuity. Using a 1.5-volt dry cell battery, connect positive battery lead to power transistor terminal No. 3 and negative lead to terminal No. 6. See Fig 1
. When battery is connected, ohmmeter should indicate continuity.
- Connect ohmmeter between power transistor terminals No. 1 and No. 3. Ohmmeter should indicate no continuity. Connect dry cell battery positive lead to power transistor terminal No. 2 and negative lead to terminal No. 3. See Fig 1
. When battery is connected, ohmmeter indicate continuity. Replace power transistor if it does not test as described.
