Repairs:

The main reasons for the horn not to ring or hoarseness are lack of battery storage, damage of horn relay and button, damage of horn, etc.The details are as follows:

1. Check the sound of the horn. If the sound is not clear and crisp, low and weak, it is mostly due to poor contact.

2. Repeatedly press the switch of the horn. If the horn sometimes rings and sometimes does not ring, most of them touch the contact points inside the switch badly.

3. Turn the steering wheel from left to right, and if there is a loud "hissing" friction, spray some grease on the relevant contact points.

4. If the horn doesn't ring at all, first check the fuse to see if it is broken, then unplug the horn and use a multimeter to measure whether there is electricity when you press the horn switch.If there is no electricity, check the horn harness and horn relay.If there is electricity, it is a problem of the horn itself. At this time, you can try to adjust the adjusting nut on the horn to see if it can make a sound.

5. If the sound of the horn is dull, it is likely that the speaker itself has a fault. At this time, as long as the speaker is tapped, most of it can be improved.All of them are in bad contact with the joints, especially the lines around the steering wheel, which are easy to wear due to frequent use.

7, horn work at low speed in cars, related to the performance of the battery, if the battery energy is reduced, the trumpet sound less, to check whether the battery storage capacity is normal.

In addition, in the horn button, can use a multimeter or view lamp to check, check the electric current to the speaker terminals, if there is current to the terminal, but the speaker did not ring, want to use the adjusting nut to adjust the speaker inside:

1. Loosen the fixed nut of the horn adjusting screw, and then turn the adjusting nut.Would be the direction of rotation as the trumpet varies according to the function, so it's hard to say which side need to move to, but must first rotate a little bit, then try it on the horn, and then further rotation.

2. Fix the adjusting nut where the horn sounds best.

3. Fix the fixing nut of the screw.

4. If the volume is insufficient, the voltage should be measured at the end of the connection horn, compared with the voltage of the battery. If the voltage is low, the connection point and line of the distribution line should be inspected.
