Horn Tone Poor

1. Harsh tone: caused by loose bolts in sheet metal mounting area.
2. Low pitch moan: caused by too high a current. Horn needs adjusting.
3. Weak tone: caused by too low a current. Horn needs adjusting.
4. Weak strained tone: foreign body in horn that should be shaken out or removed.
5. Harsh vibration: caused by horn contacting sheet metal. Bracket should be bent to give horn clearance and freedom from interference.
