TROUBLESHOOTING
1. If the horn does not sound or fails to function satisfacto-
rily, check for the following conditions.
a. Discharged battery.
b. Loose, frayed or damaged wiring leading to horn ter-
minal.
2. If battery has a satisfactory charge and wiring appears to
be in good condition, check for the following.
a. Poor ground to frame through mounting hardware or
ground wire (see Steps 3-5 below).
b. Inoperative horn switch (see Steps 3-5 below).
3. Remove terminal clips from connections.
4. Connect a voltmeter as follows.
a. Positive (+) lead to wire terminal.
b. Negative (–) lead to ground.
5. Turn ignition switch to IGN. Depress horn switch. If bat-
tery voltage is present, horn or horn grounding is faulty. If
battery voltage is not present, either horn switch or wiring
to horn is faulty.
a. If horn is faulty, then it must be replaced as an
assembly. The horn is not repairable.
b. If horn switch is faulty, replace left handlebar switch.
