Motorcycle horns are generally a non-repairable item and must be changed out when they malfunction. Some horns have an adjustment screw allowing some troubleshooting of the horn. When changing out a horn, the wiring is simple and straightforward. The wiring consists of a positive wire, which is routed through the horn switch, and the ground wire. How long it takes to wire a motorcycle horn will vary depending upon skill level, but it generally takes 30 to 60 minutes to complete.

Disconnect the negative terminal of the motorcycle battery with an appropriate-sized SAE or metric open-ended wrench.
Step 2
Connect the horns red wire to the positive horn connection in the motorcycles wiring harness. The method of connection will vary depending upon motorcycle make and model, but will generally consist of a contact screw. Tighten the screw with an appropriate-sized screwdriver or open-end wrench.
Step 3
Connect the horns black or green ground wire to the ground connection in the motorcycles wiring harness.
Reconnect the negative terminal to the motorcycle battery.
