Where is the starting relay of Nissan Qi Jun?

Qi Jun electronic fan relay is located in the relay box next to the engine compartment fan. Relay is an automatic control device. When the input (electricity, magnetism, sound, light and heat) reaches a certain value, the output will change by leaps and bounds. Automobile relay is a relay used in automobile, which has high switching load power and strong shock and vibration resistance. The following is the working principle of the relay: 1. When a certain voltage or current is applied to both ends of the coil of the electromagnetic relay, the magnetic flux generated by the coil passes through the working air gap of the iron core, yoke, armature and magnetic circuit to form a magnetic circuit; 2. Under the action of the magnetic field, the armature attracts the pole face of the iron core, thus pushing the normally closed contact to open and the normally open contact to close; 3. When the voltage or current at both ends of the coil is less than a certain value and the mechanical reaction force is greater than the electromagnetic attraction force, the armature returns to the initial state, the normally open contact is disconnected, and the normally closed contact is connected.
