Motorcycle horn button works in two ways: First, the electrical horn two connecting wires, a battery and the ignition switch is connected to the positive electrode, and the other is connected to the horn button, and then through the horn button static and dynamic ground contact, communication and electric horn operating circuit, the electric horn to work. Second, the two connecting wires of electric horn, a ground, and the other is connected to the horn button, and then through the horn button static DC power outlet lock movable contact is connected to the ignition switch, electric horn operating circuit communication , the electric horn to work, is to use a small relay as an example, the installation method.

Horn button is a way of working: First, disconnect the electric horn and the horn button connecting wires, a wire conductor and the relay coil end of the connection. Second, the other end of the line and the ignition lock DC relay coil is connected to the outlet. Third, the relay movable contact ground, the normally open contact connected to termination of the original horn and horn button is connected.

Horn button is working way: First, a relay coil of wire is connected directly to ground. Second, disconnect the electric horn and the horn button connecting wires, the wire and another wire end of the relay coil is connected. Third, the relay movable contact connected to the ignition lock DC outlet, the normally open contact connected to terminals connected to the original horn and horn button is connected.
