What is the reason for the Civic's charging system check and the horn not working?
1 Answers
Civic horn not working may be due to contact erosion. Contact erosion: If the horn is pressed for a long time, it can easily cause the horn contacts to erode and generate impedance. The current flowing through the electromagnetic coil weakens, the electromagnetic suction decreases, and it cannot attract the armature to drive the diaphragm to vibrate normally, resulting in a hoarse sound or even no sound. However, when the horn is pressed continuously, if a strong instantaneous current passes through the impedance, it can still work normally, so it may work intermittently. Poor sealing can easily lead to moisture. Although the inside of the horn is sealed, if the sealing is not tight, fog may enter during car washing or there may be water vapor in the internal air space. Water vapor can easily cause the contacts to become damp and fail to work properly. Poor contact of the electromagnetic coil terminal: Some horns have internal electromagnetic coil enameled wire terminal connections made of aluminum metal rivet crimping, rather than firm soldering. If the insulating paint on the enameled wire end is not completely removed or the rivet crimping is not firm, it can easily cause a virtual connection fault, leading to poor horn performance.
