16 where is the Nissan sylphy relay?

Pacific Auto Network is in the fuse box behind the engine compartment battery. Press the horn button, the current will flow to the electromagnetic coil of the horn relay through the loop, and the electromagnetic coil will attract the moving contact switch of the relay to close, and the current will flow to the horn.

Deploy it all in the fuse box behind the engine compartment battery.

Press the horn button, the current will flow to the electromagnetic coil of the horn relay through the loop, and the electromagnetic coil will attract the moving contact switch of the relay to close, and the current will flow to the horn. The current makes the electromagnet in the horn work, making the diaphragm vibrate and make a sound.

Relays are generally composed of iron core, coil, armature and contact reed. As long as a certain voltage is applied to both ends of the coil, a certain current will flow in the coil, thus generating an electromagnetic effect. Under the attraction of electromagnetic force, the armature overcomes the pulling force of the return spring and attracts the iron core, thus driving the moving contact of the armature to attract the stationary contact (normally open contact).

Extended data:

Horn relay has three legs and four legs.

One, three legs

1. Unplug the non-grounding wire from the horn and connect it to the terminal marked "button" of the relay. The grounding wire of the horn will not move.

2. Connect the terminal marked "Battery" of the relay to the positive pole of the battery with wires.

3. Connect the terminal marked "Horn" of the relay to another terminal on the horn with a wire.

4, relay shell grounding.

Two, four legs

1, the four-pin relay has two large terminals and two small terminals, which are inserted in the relay seat.

2. Connect any big terminal with any small terminal, which is called point A ... and the other big terminal is point B..

The other small terminal is point C.
