Confirmation Step 3: Antenna System Simple Inspection

CONFIRMATION STEP 3: ANTENNA SYSTEM SIMPLE INSPECTION [RADIO]

- Because the antenna system is equipped with a capacitor, the continuity cannot be checked. Therefore proceed to the following simple inspection.

- Turn the AM radio on.
- Tune to the frequency with no broadcast and listen for a buzzing sound.
- Turn a hand-held light on and shake it around the antenna rod (around 10-20 mm {0.40-0.78 in})
- If a whirring sound from the speaker synchronized to the work light movement is confirmed, the antenna system is normal.
NOTE:
- Use a fluorescent light type for the inspection. Accurate diagnostic cannot be done with an incandescent light.
