  1. Connect analog ohmmeter leads between power transistor terminals No. 3 and 8. Ensure ohmmeter positive lead is connected to terminal No. 3. Ohmmeter should indicate no continuity. Using a 1.5-volt dry cell battery, connect positive battery lead to power transistor terminal No. 7 and negative lead to terminal No. 3. Perform STEP 1. See Fig 1 . When battery is connected, ohmmeter should indicate continuity.
  2. Connect ohmmeter between power transistor terminals No. 1 and 3. Ensure ohmmeter positive lead is connected to terminal No. 3. Ohmmeter should indicate no continuity. Connect 1.5-volt dry cell battery positive lead to power transistor terminal No. 2 and negative lead to terminal No. 3. Perform STEP 2. See Fig 1 . When battery is connected, ohmmeter should indicate continuity. Replace power transistor if it does not test as described.
