id0903e3804200

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

  1. Turn the AM radio on.
  2. Tune to the frequency that there is no broadcast and you will hear a buzzing sound.
  3. Turn a fluorescent light on and shake it around the antenna rod (around 10—20 mm {0.40—0.78 in})
    Note
    • Use a fluorescent light type for the inspection. Accurate diagnostic cannot be done with a different type of light.

  4. If a whirring sound from the speaker synchronized to the work light movement is confirmed, the antenna system is normal.
