What Causes One of the Car Snail Horns to Stop Working?
1 Answers
Car snail horns may have one working and the other not due to the following reasons: 1. Poor sealing leading to moisture: The horn is internally sealed, but if the sealing is not tight, moisture may enter during car washing or water vapor may be present in the internal air space. This moisture can easily cause the contacts to become damp and fail to function properly. 2. Poor contact at the electromagnetic coil terminals: Some horns have electromagnetic coil enameled wire terminal connections made with aluminum metal rivets instead of secure soldering. If the insulation paint on the enameled wire ends is not properly removed or the rivets are not tightly pressed, poor contact can occur, leading to malfunction. This issue is due to the horn's quality and cannot be repaired; only replacement is possible. 3. Contact point erosion: Prolonged use of the horn can cause the contacts to erode, creating impedance. This weakens the current flowing through the electromagnetic coil, reducing the electromagnetic force and preventing the armature from properly vibrating the diaphragm. This results in a hoarse sound or complete failure. However, when the horn is pressed repeatedly, a momentary strong current can still pass through the impedance, allowing intermittent operation, hence the sporadic functionality.
