Power Transistor (Sonata)
- Remove connector from power transistor. Apply 1.5 volts (one dry cell battery) between power transistor terminals No. 1 and 2. See Fig 1 .
- Check continuity between terminals No. 2 and 3 with terminal No. 1 disconnected and connected. With terminal No. 1 disconnected, no continuity should be present. With terminal No. 1 connected, continuity should be present.
