Operation CHARM: Car repair manuals for everyone.

Horn Tone Poor

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