Adjust the horn current until the horn current
is between 4.5 amps and 5.5 amps (12 volts).
• | Perform the adjustments in ¼ turn (90 degree)
increments. |
• | Loosen the adjustment screw locknut. |
• | Turn the adjusting screw counterclockwise in order to increase
the current. |
• | Turn the adjusting screw clockwise in order to decrease the current. |
Cold Weather Adjustment
• | If the horn fails to sound in cold weather, the current limit
may be set too low, even if the horn is still within the amperage limit. Do
not make this adjustment unless the horn fails to sound in cold weather. A
current increase on a properly functioning horn may result in damage to the
horn. |
• | Turn the adjusting screw ¼ turn (90 degrees)
counterclockwise in order to increase the current draw until the horn sounds. |
