The reason why the motorcycle horn does not sound is:
1. Loose sealing is prone to moisture. Although the horn is internally sealed, if the seal is not tight, entering mist or water vapor in the air during car washing can easily cause the contacts to become damp and not work properly. Solution: Check the sealing, replace the sealing strip in a timely manner, and clean the internal water vapor.
2. Poor contact of the solenoid coil terminal. Some horn internal electromagnetic coil enameled wire terminal joints are aluminum metal rivet crimped connections, which are not securely welded. If the insulation layer on the enameled wire at the end is not cleaned or the rivet crimping is not secure, it is easy to cause virtual connection faults, leading to poor horn operation. Solution: It cannot be repaired and can only be replaced with new parts.
3. Contact erosion. If the horn is pressed for a long time, it can easily cause the horn contact to burn and generate impedance, weaken the current flowing through the electromagnetic coil, and decrease the electromagnetic suction force, which cannot attract the armature to drive the diaphragm to vibrate normally, resulting in hoarse pronunciation. Solution: Go to the repair shop to replace the contact points, but the owner is personally unable to handle them.
4. Open circuit or short circuit in the power cord. Causing the motorcycle horn to not sound. Solution: It is recommended that car owners go to a 4S store or repair shop for testing or repairing the power cord.
5. Poor contact or grounding of the horn button. Causing the motorcycle horn to not sound. Solution: It is recommended that car owners go to a 4S store or car repair shop in a timely manner to inspect or repair the horn button. If the horn button is severely damaged, it should be replaced with a new one in a timely manner.
6. The horn terminal is loose. Causing the motorcycle horn to not sound. Solution: It is recommended that car owners go to a 4S store or car repair shop in a timely manner to inspect or repair the horn terminal. If the horn terminal is severely damaged, it should be replaced with a new one in a timely manner.
7. The gap between the horn armature is too large or too small. Causing the motorcycle horn to not sound. Solution: It is recommended that the car owner go to a 4S store or repair shop for repairs. If the car owner is unable to solve this problem personally, it may cause new problems in the car and cause unnecessary losses.
8. The storage capacity of the battery is too low. Causing the motorcycle horn to not sound. Solution: Replace with a new battery or charge the battery.
9. The horn is broken. Causing the motorcycle horn to not sound. Solution: Car owners should check and replace their horns in a timely manner. If the owner is unable to complete the inspection and replacement personally, they can go to a 4S store or car repair shop for testing and replacement.
10. The horn adjustment screw is loose. Causing the motorcycle horn to not sound. Solution: It should be adjusted and tightened.
