The speaker failure check

The car horn is not a frequently used device is sometimes necessary, but not wishful ringing or makes strange sound, very big sense of confusion.
The horn chirp big reasons for the poor are poor contact. Wherein, in particular the steering wheel around each contact, due to prolonged use, so that contact poor contact. Check the fault of the speaker, left and right to turn the steering wheel, if this case a larger the hissing friction sound, mostly contact surface is not smooth. To solve this problem, it can be removed to the upper cover of the steering column, injection grease to the contact portion. So most of them can reduce the hissing sound of friction, can also improve the response of the speaker.
For thorough maintenance of the speakers push switch contacts, it is necessary to remove the steering wheel itself to clear the dirt on the contacts, re-coated with a layer of grease, so that we can significantly improve the conductive contacts, which can be assured by move the car horn.
Check the speaker of the song, if you feel song not ringing, low and weak, are contacts of a bad contact.
Repeatedly pressing the switch, pressing the speaker if the speaker sometimes ringing, sometimes not ringing, mostly pressing the switch contacts within the contact is not good.
Left and right to turn the steering wheel, larger the hissing friction sound, injected some grease to the contact site.
If the speaker is completely sound, is likely to be a fuse is blown, check the fuse. Speaker power cord, to find the speaker's power cord, the wiring of the power cord plug disassembly, check whether there is poor contact.
If the horn chirp dull, very horn itself is faulty, then as long as the horns knocked most of them can be improved.
