  1. Disconnect power transistor connector. Using an analog ohmmeter, connect positive ohmmeter lead to terminal No. 7 and negative lead to terminal No. 3. See Figure -Figure . Ensure there is no continuity.
  2. Using a 1.5-volt dry cell battery, connect positive end of 1.5-volt battery to power transistor terminal No. 6 and negative end to terminal No. 3. Ohmmeter should now read continuity between power transistor terminals No. 7 and No. 3.
  3. Connect positive end of 1.5-volt battery to power transistor terminal No. 2 and negative end to terminal No. 3. Connect positive ohmmeter lead to terminal No. 1 and negative lead to terminal No. 3. Ohmmeter should read continuity. Replace power transistor if it does not test as described.
