1. After connecting the line, press the horn button, the horn will not sound, and the relay will not clatter.It means that the blue line / white line / button line is not connected correctly. The correct method: the blue line is connected to one line of the button, the other line of the button is connected to the battery positive pole, and the white line is grounded to the frame.
2. The air pump makes a whine sound but the horn doesn't sound, which means that the positive and negative terminals under the air pump are connected reversely. The yellow wire should be inserted into the positive pole and the black wire into the negative pole.
3. The sound of the horn is not stable, and sometimes it will break. That's because there is paint on the frame where the black wire is grounded, which affects the normal power on of the negative pole. As long as it is connected to a good power on position, it is OK.
