Where is the fire wire of the automobile generator

1. The automobile generator has three or four wiring columns, the thickest is the fire wire B, which is directly connected to the positive fire wire of the battery, and the thinner one marked with F is The magnetic field is connected to the column, connected to the output end of the regulator, and the other marked with E is the grounding (iron), which can be connected to iron or battery and iron wire. The four lines marked with N are neutral points, which can generally be unconnected.

2. Some models are built-in regulators, and the connectors behind the generator are marked with B, IG, L, E (-). Among them, the B junction column is the output, and LG is the fire wire from the ignition switch, which provides a fire wire for the internal adjustment.

3. Does the questioner want to ask whether the fire wire of the parking generator is connected to the positive pole or the negative pole? The fire wire controlled by the electric fire lock is connected to the generator's F column, and the B column of the generator is connected to the positive pole of the battery through the starter.

4. The positive pole of the fuse relay box or battery. The main fire line refers to the wire transmitted by electricity. In the Mondeo generator, the main fire line is connected to the positive pole of the fuse relay box or the battery. The combination of these lines greatly increases the function of the generator.

5. The generator can work normally. The specific operation steps are as follows: place the generator on the desktop. The leftmost B+ pin is the line connecting the positive pole of the battery. The F pin is the positive pole connecting the regulator. The E pin is the iron connecting the regulator. Finally, the rest is the pins that connect the vehicle to the iron.

6. + is the output end of the generator, the positive pole connected to the battery or the power supply fire wire, - is the iron end, the negative pole connected to the battery or the common iron. F is the magnetic field input terminal, and the f column of the regulator is connected to control the magnetic field current and stabilize the output voltage.

Car to fireIs there a saying about the thickness, thinness and length of the wire?

The car ignition wire is generally 3 meters appropriate. If the ignition wire is too long, it will increase the resistance and consume power. If it is too short, it is not easy to connect. When the car battery loses power, it will affect the power supply system of the whole vehicle, making it difficult for the car to start the battery electrodes connecting the two cars with a 16-square copper wire. , then start another car to make its engine idle, and try again.

There are two ways to express the thickness of the wire. One is to express the cross-sectional area of the copper core of the wire; the other is to express the diameter of the copper core. If it is expressed in the diameter of the copper core, 8mm copper core wire should be used for gasoline vehicles, and 12mm copper core wire should be used for diesel vehicles.

When purchasing, it is not only related to the thickness, but also to the length. If the wire is too long, it is easy to consume power, resulting in the vehicle being unable to start. Generally, it is recommended to choose a 3-4-meter-long wire.Besides, don't choose a wire that costs dozens of yuan. Its quality is very unreliable, which is not only easy to leak electricity, but also may damage the car.

When buying, it is not only related to thickness, but also to length. If the wiring is too long, it is easy to lose power and cause the vehicle to fail to start. It is generally recommended to choose a 3-4-meter-long wiring. In addition, don't choose overhead wires that cost dozens of yuan, because their quality is very unreliable, which is not only easy to leak electricity, but also may damage the car.

The ignition wire does not need to be too thick. First, the battery cannot provide 1000A current in any case. Second, the ignition time is very short, and those calculation formulas are for calculating long-term power supply. The one marked on Taobao can probably be used to drive a shovel. Introduction: Ordinary cars, depending on the displacement and engine model, the starting current is also different.

What is the red line of the car

Hello, generally speaking, we will use red to represent the line of fire, which is represented by the letter l.

Hello, if the wire is red, it represents the fire wire, which is represented by the letter l. If the wire is blue or black, it represents the zero wire, which is represented by the letter n, which belongs to the neutral wire. If the color of the wire is yellow and green two-color wire, it represents the protective neutral wire, which is called the insulated wire, that is, the ground wire.

How to connect the fire wire of the car battery (Operation Guide): (1) First, clamp the red wire of the starter cable over the positive pole of the red battery of the rescued car. ( 2) Then clamp the red wire at the other end on the positive pole of the red battery of the ambulance. ( 3) Clamp the black wire on the black negative battery of the rescued car.

The red line is the fire line, the black line is the iron wire, and the gray, purple, yellow and green are generally the control line in the harness sheath, which controls the automobile electrical appliances, insurance and display. There is no unified regulation for automobile harnesses, but there is generally a shallow confirmation. They represent the lead-out function of the controller respectively.

Red is the fire line; blue is the zero line; yellow is the ground line. The fire wire is the power cord, and there is electricity before the circuit is turned on. The blue line is the zero line, and there is no electricity before the circuit is connected. The green wire is a ground wire, which is used for grounding and plays a protective role. There is no electricity.

Ignition and start system: white (W) power supply system: red (R) light signal system (including turn indicator light): green (G) car wire is also known as low-voltage wire, which is different from ordinary household wire. Ordinary household wires are copper single wires with a certain hardness.

What are the requirements for the car fire line

Generally speaking, the wire used for the car battery fire line should meet the national standard. The specific regulations are that the car battery fire line should use a copper core with a cross-section of 5 square millimeters. Line.

Car fire wire generally uses 16 square meters, truck 25 square meters copper wire, and heavy trucks 35 square meters copper wire. Because the starting current of the engine is large, and the battery voltage is low and the current is greater, so the smaller the resistance of the fire wire, the better. When the battery of the car loses power, it is difficult for the car to start, and the loss of the battery will also affect the power supply system of the whole car.

Generally speaking, the ignition line of a car is about 3 meters. It should be noted that the ignition line should not be too long. If it is too long, it is easy to increase the resistance and consume too much electricity.When the battery of the car is out of power, it is difficult for the car to start, and the loss of the battery will also affect the power supply system of the whole car.

The starting current of the engine is large, and the battery voltage is low and the current is greater, so the smaller the resistance of the fire wire, the better. Use 25 square copper wire. The details are as follows: (1) First, clamp the red wire of the starting line on the positive pole of the red battery of the rescued car.

What are the requirements for the car ignition line? Generally, the ignition line of a car is about 3 meters. It should be noted that the ignition line should not be too long. If it is too long, it is easy to increase the resistance and consume too much power. When the battery of the car loses power, it is difficult for the car to start, and the loss of the battery will also affect the power supply system of the whole car.

16 square copper wire for small cars and 25 square copper wire for trucks. That is to say, 16 square meters of the battery and the fire line are just enough.However, if it is a large engineering vehicle, it has to be mentioned separately. The recommended national standard pure copper is 25 square meters. If it is lower than the recommended value, it will be difficult to start the engine.

Car fire line connection method

First of all, open the protective cover of the battery, and then clamp the positive pole of the battery at the red end of the fire wire. At this time, the positive pole is connected to the positive pole, and the voltage of the general vehicle battery is 12v. , you can rest assured to operate.

The correct way to connect the fire wire of the car battery is to connect the red wire pliers of the starting line to the positive pole of the car red battery, and cannot be reversed.

Confirm that the battery that is out of power has the same voltage as the battery responsible for rescue. Arrange the vehicle so that the two car batteries are close enough to facilitate the connection of the cables.Turn off the engines of the two vehicles. Open the hood of each car. Turn off the headlights, wipers, radios and all accessories of the two cars.

The method of igniting the car battery is as follows: Note that the engine, audio and air conditioner of the two cars need to be turned off before connecting. First, clamp the red wire of the start-up wire over the positive pole of the red battery of the rescued car.

Battery b "-" directly connects to the frame. Car powering refers to the way to connect the circuit of a nearby normal car to the target power loss battery to start the car. Be sure to turn off the engine before wiring and borrow electricity. Pay attention to compare the parameters of the batteries of both sides to see if the specifications are close.

When the battery of the car runs out of power, it is difficult to start the car, and the power loss of the battery will also affect the power supply system of the whole car. In this case, the car can be started by using the fire line.

Which color line on the car is the fire line? Which one is the zero line?

The mainland generally uses brown to represent L, and the English abbreviated as L (LIVE) line, that is, the fire line; blue represents the N (NEUTRAL) line, that is, the zero line; yellow and green (commonly known as the flower line) represents the ground line (E line).

Gray, blue and yellow-green are generally the fire line, blue is the zero line, and yellow-green is the ground wire, which belongs to the connection method of professional electricians. In mainland China, red is generally used to represent the L line, that is, the fire line, blue represents the N line, that is, the zero line, and yellow and green to represent the ground line.

Hello, if the wire is red, it represents the fire wire.It is represented by the letter l. If the wire is blue or black, it represents the zero wire. It is represented by the letter n, which belongs to the neutral wire. If the color of the wire is yellow and green two-color wire, it represents the protective neutral wire, which is called the insulated wire, that is, the ground wire.

The color of each line in the indoor electrical line. The protective ground wire (PE line) should be yellow-green, and the zero line should be light blue; phase line: phase A-yellow, phase B-green, phase C-red. Black and white can be used for lighting control lines. The color selection of the wire insulation of the same building should be consistent.

Red, yellow and blue represent the fire line, black represents the ground line, and yellow and green represent the zero line. L.N.E are: fire, zero and earth respectively.

The color of the ground line fire line zero line is as follows: the color of the fire line is red, brown, yellow, green, etc.;The color of the ground line is generally yellow and green two-color line; the color of the zero line is black and blue. In general life, the fire line is red, the zero line is blue, and the ground line is yellow and green, and the usage rate is high.
