3S-2 HORN SYSTEMS
(10) Connect a jumper lead from horn base to the
vehicle chassis or engine and repeat the above tests.
(11) If horn now operates, remove attaching screw,
horn and mounting bracket, clean mating surfaces.
(12) Install horn, mounting bracket and attaching
screw, tightened screw to 15 foot-pounds (20 N*m)
torque.
(13) If horn still does not operate, horn is inoperative
and must be replaced.
(14) To check for bad component ground, place a
voltmeter between component and ground. If a sizable
voltage is shown on the meter, repair the poor ground
connection.
(15) Continuous horn operation is usually caused by
improper ground in horn ring or button wiring.
HORN ADJUSTMENT
Adjust current by turning the adjusting screw
counterclockwise to decrease the current until the speci
fied current is reached. Current adjustment is very sen
sitive. Therefore, care must be taken not to turn the
horn adjustment screw too far. Turn only 1/10 of a turn
at one time.
(1) Check for normal battery voltage (about 12.6
volts).
(2) Connect ammeter in series between horn and
battery and read current as shown in figure 3S-2.
(3) Adjust current to 4.5 amps.
NOTE: Do not stuffrags or other materials in the horn
protector to muffle the sound while adjusting, as this
changes the vibration frequency and would give a raise
in current setting. When adjusting a set of horns, each
horn should be connected and adjusted separately, then
check for tone by operating as a pair.
