Power Transistor (2.0L) Test

  1. Using an ohmmeter, connect ohmmeter leads between power transistor terminals No. 1 and 3. Using a 1.5-volt dry cell battery, connect positive battery lead to power transistor terminal No. 2 and negative lead to terminal No. 3. Perform TEST 1. See Fig 1 .
  2. When dry cell battery is connected, ohmmeter should read continuity and when disconnected no continuity.
  3. Connect ohmmeter between power transistor terminals No. 6 and 3. Using a 1.5-volt dry cell battery, connect positive battery lead to power transistor terminal No. 5 and negative lead to terminal No. 3. Perform TEST 2. See Fig 1 . When dry cell battery is connected, ohmmeter should read continuity and no continuity when disconnected.
  4. Replace power transistor if it does not test as described.
