12 where is the gasoline pump insurance for Nissan hacker?

Nissan hacker fuse box is on the left side of the cockpit, and you need to open the door to open the fuse box cover. The hacker electronic fan fuse is located in the engine compartment fuse box. The working principle of electronic fan is that the automobile electronic fan is controlled by thermostat. When the water temperature rises to the upper limit, the thermostat turns on the power supply; when the water temperature drops to the lower limit, the thermostat turns off the power supply and the fan stops working.

Introduction of electromagnetic relay

Electromagnetic relay generally consists of iron core, coil, armature and contact reed. As long as a certain voltage is applied to the two 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 and the static contact of the armature to attract each other. When the coil is powered off, the electromagnetic attraction disappears, and the armature will return to its original position under the reaction of the spring, so that the moving contact and the original static contact attract each other.

In this way, it is attracted and released, so as to achieve the purpose of making and breaking the circuit. For the normally open contacts and normally closed contacts of relays, we can distinguish them as follows: the static contacts that are disconnected when the relay coil is not energized are called "normally open contacts"; Static contacts in the on state are called "normally closed contacts".
