1. Contact ablation: If the
Used Car horn is easily in contact with the Used Car horn for a long time, impedance will be generated. The current flowing through the electromagnetic coil will weaken, and the electromagnetic attraction will not attract the armature to drive the diaphragm to vibrate normally, which will cause hoarseness or even no noise. But when the
Used Fuel Car horn is pressed continuously, if the instantaneous strong current passes through the impedance and can still work normally, it is good or bad.
2. Poor sealing and easy to be affected by moisture: Although the interior of the Used
Fuel Car horn is closed, if the Used Car is not sealed tightly, there is water vapor in the mist or in the air in the internal space, which can easily cause the contact to be damp and unable to work properly.
3. Poor contact of the solenoid terminal: Some of the internal solenoid coil enameled wire terminal joints are crimped with aluminum metal rivets, and the welding is not firm. If the insulating paint on the end enameled wire is not clean or the rivet is not pressed firmly, it is very easy to cause a virtual connection failure, resulting in poor operation of the Used Car horn. This failure is caused by the quality of the Used Car horn and cannot be repaired, but only replaced with new parts.
