Car horn is not a frequently used device, but sometimes necessary, is not wishful to ring or send a strange sound, the light who is angry, were not conducive to heavy security. Case: Speaker dumb My car horn goes wrong, sometimes clearly by the speakers, speaker but is almost silent. Occasionally, the ring, and also with the mosquito sound like, listen carefully, it seems to have mixed with the sound of friction. I ask, What is the causes, diagnosis and treatment of this disease to do? Diagnosis: Check car horn body This end, Automotive Maintenance Net consulted Auto Repair Expert Mr Hu. On the Necessity and that the car horn if these symptoms occur, mostly poor contact, especially the steering wheel around which all contact, due to the use of time is too long, easily so that contact failure. So, what is the car horn sounds it? Hu Jianjun said, when the horn button is pressed, current will flow from the battery horn relay coil, due to become a magnet, it will relay to open joint closed, current will flow from the Battery Division Speaker Division. As the speaker's role within the solenoid diaphragm vibration Ershi sound. Check the speaker's song, if the song was not crisp, low and weak, mostly poor contact contacts. Repeatedly pressing the horn switch, if the horn sounded at times, sometimes not ringing, pressing the switch are mostly good contacts within the contacts. Turning left and right steering wheel, if there is a large "hissing" sound of friction can be related to the contacts to the injection site of some grease. If speakers do not ring, it may be blown fuse, check the relevant fuse; also be speaker of the power line problems. Find the speaker's power cord, plug the power cord connection disassembly time, check for poor contact. If the speaker of the song boring, is likely to trumpet their own faulty, then knock on the stroke of a speaker, most of them can be improved. In addition, horns button, you can view the lights with a multimeter or to see to see if there is no flow of power to the speaker terminals Road Department, if there are current to the terminal office, but the speaker does not ring, the use in speaker inside the adjusting nut to adjust. 1. The speaker to adjust the fixed nut loosen the screw, then turn about adjusting nut. The direction of rotation function because of the speaker vary, it is difficult to say which side to turn, but must first turn a little, then honk test to see, and then further rotation. 2. The best place in the horn fixed adjustment nut. 3. Screw fixed to the fixed nut to live. 4. If the volume is insufficient to connect the speaker terminal voltage is measured, and compared to battery voltage, if the voltage is low, then, to view the connection point and the circuit wiring. Detected by the above, no loud speaker on the incurable disease, and work should pay attention to the contact erosion and Connector Poor contact problem, sometimes not properly handled to detours, especially when dealing with speaker sound does not ring when the issue is more to note. Whistle child when CAREFUL IN THE SUMMER Mr. Wang told us that if he really can fix a car horn, his horn to celebrate the festival chairman. Of course, this is Wang Jun's a joke, it is conceivable, speakers do not sound normal trip has brought him a lot of trouble.
