Why does the Besturn B50's alarm horn keep sounding?

[LillianLynn]

Besturn B50's alarm horn frequently sounding may be caused by the following reasons: 1. Horn relay sticking causing continuous horn sound: This fault is easy to identify. Just locate the horn relay and when the horn sounds, gently tap the relay with a screwdriver or other tool. If the horn stops, simply replace the relay. 2. Internal sticking or short circuit in the horn switch: This can cause the horn to sound continuously. For this fault, you need to disconnect the horn switch wires to check if the switch is the cause. If it's caused by wiring issues (such as the horn wire connecting to the live wire), it will also result in continuous sounding.
