Horn for auto

Electric system auto parts: Horn

In Great Britain each vehicle that has capacity at least of 50cc must be equipped with a horn. Using the horn, driver can warn other road users about the threat. Also horn can be used as warning before overtaking, but only outside localities. Horn loudness is strictly regulated: 105 decibel at a distance of 7 meters. In some countries permissible loudness may be higher. Pay attention to this fact when you buy a car.

If there is a technical failure of the horn, there is no sound. Though there may be a problem with button or wire. That is why before substitution you need to make a functional test. Many of car tuning fans install new horns, because they don’t like the sound of the old ones. In different cars horn position is different. Its substitution is really easy. In the majority of cases you need just to take out the pin and to unscrew some bolts. Sometimes signal device is fixed with a wire strap.

Before you start to equip your car with a new horn, test the new model. You need to take into account that new horn requires place. Some tuned models are very big and don’t fit any car. As a rule, to reveal possible problems is enough just to make a visual examination. In our online shop you can also order fender, gas tank, manifold, heat sensor of coolant, clutch plate or fog headlamps. Perhaps, you need some spares, ignition cable or calliper for example. Our Internet shop is always at your service.

  • horn is jammed in active position;
  • electric wiring is broken.

  • horn sound is barely heard;
  • only one signal is functioning.

Causes of horn malfunctions

  • contacts are oxidized or damaged;
  • fuses are burnt;
  • relay failed;
  • water got inside the system;
  • contacts are broken;
  • short-circuit of wiring.

Diagnostics

First of all determine the breakage kind. Press the horn button. If in this case the lamp of passenger compartment light fades, the cause of malfunction is in short-circuit of wiring.

To test, if the signal works correctly, connect a lamp of 12 V voltage instead of it. Press the signal button. The horn is broken, if the lamp lights up.

Also check the horn fuse. Look for its location and number in technical documents of the car.

If the vehicle is equipped with airbags, you must make sure that they are packed correctly. If the airbags are packed incorrectly, it can be an obstacle for the horn contacts situated under the steering wheel. Airbags must be checked only by experts: driver’s and passengers’ safety depends on how correctly they are packed.

Besides, you should check the clock spring. In case it is out of service or deformed, the quality of signal can decrease.

Replacement and repair of horn

In case if wiring is cut or damaged, you should replace it. To find out which contact exactly is broken, you can measure voltage of each one. Although, in most situations all wires are replaced at once.

Sometimes contacts and terminals of the mechanism are cleaned to eliminate horn malfunctions. As a preventive measure exposed wires and contacts must be lubricated by special substance, which prevents them from oxidizing.

Main signal is situated near the radiator of a vehicle. It will not take a lot of time to replace the horn. For that, disconnect fasteners and contacts of the old part and connect a new one. If non-original components are used, than they must be adjusted. For this, contact a service station.
