Adjust the horn current until the horn current is between 4.5 A and 5.5 A:

1. Turn the adjusting screw (1) clockwise in order to increase the current.
2. Turn the adjusting screw (1) counterclockwise in order to decrease the current.
3. Do not turn the adjusting screw (1) too far.

Turn the adjusting screw 1/4 turn at one time.

If the adjustment excessively loosens the adjusting screw (1), stake the adjusting screw (1) with a punch.
