Electrical Control Gas Horn Instruction Manual

1. This product is suitable for all vehicles with air source devices.

The working current of the control relay must be greater than 10A.

3. The main power cable of the relay should have a cross-sectional area greater than or equal to 2.5MM2. The output cable should not be less than 1.5MM2. The negative (grounding) cable should have good contact to ensure the effectiveness of this product.

4. The air source for the horn should be directly introduced from the air tank to achieve better sound quality: The air tank must be regularly discharged to prevent water from affecting the service life of the electromagnetic valve.

5. Working pressure: 0.3~0.9MPa, Ideal pressure: 0.42~0.68MPa.

The temperature range is -40 to 80 degrees Celsius.

The product has a service life of more than 100,000 times.

Electromagnetic Valve Usage Notes:

Electromagnetic valve air tube joints should be carefully tightened. During use, the filter mesh may sometimes become clogged, and it should be cleaned regularly to avoid affecting the sound quality. 

Common Car Horn Faults and Their Solutions

     The car horn is a frequently used device when driving, and if the horn fails, it will be very inconvenient to drive.

     Let's take a look at how the horn works. When you press the horn button on the steering wheel or anywhere else, current from the battery flows through the circuit to the electromagnetic coil of the horn relay. The electromagnetic coil attracts the moving contact of the relay to close the circuit, and the current then flows to the horn. The current makes the horn's internal electromagnet work, causing the vibration membrane to vibrate and produce a sound.

     In many cases of horn failures, the problem often lies with the horn itself. Especially in cars with certain designs, the location of the horn installation can be defective, making it easy for the horn to get wet in the rain, leading to damage. When a problem occurs, you can refer to the following steps for inspection.

     Sometimes the horn does not respond when the switch is pressed. If the horn sometimes sounds and sometimes does not, it is often due to poor contact points within the horn switch, or sometimes the problem is with the horn itself.

The hoarse voice is often due to poor contact of the plug, especially the contact points around the steering wheel, which are prone to wear due to frequent use.

     First, check the fuse to see if it has blown. Then, remove the horn plug and use a multimeter to check if there is electricity here when the horn switch is pressed. If there is no electricity, you should check the horn wire harness and the horn relay; if there is electricity, it is a problem with the horn itself. At this point, you can also try to adjust the tuning nut on the horn to see if it can make a sound. If it still does not work, you need to replace the horn.
