How are the car cables connected? Let’s take a look together.
For vehicles with a negative pole on the body, it is recommended to connect the positive pole first, and then connect the negative pole. In fact, there is no mandatory management rule. It is just that you connect the positive terminal first and then the negative terminal so that we will not have a short circuit. If the negative pole is connected first and the iron is grounded due to improper operation during the connection of the positive pole, the circuit will be damaged. There is no order, just don’t do it the other way around! Don’t make it too thin, otherwise it will be blurry from the beginning!

Remember red and black, black and red are simple red + black - means to connect the spare battery first, black - red + means to connect the car battery. For vehicles with a negative pole in the body, it is recommended to connect the positive pole first and then the negative pole. In fact, there is no mandatory rule. Just connect the positive terminal first and then the negative terminal, so that there will be no short circuit. If you connect the negative pole first and ground the iron due to improper technical operation during the process of connecting the positive pole, this will damage the circuit and the circuit. There is no order, don't reverse it! Don't make it too thin or it will be mushy from the beginning! Remember, red and black, black and red, this is simple. Red + black - connect the backup battery first; black - red + connect the car battery first.
What are the precautions for car connection lines? Let’s take a look together.
It is not difficult to connect the battery to the car, and you just need to be careful not to mix the positive and negative poles or short-circuit the positive and negative poles. Remember to connect the positive pole to the positive pole and the negative pole to the negative pole. This is the charging connection method to charge a dead car.
The charged line will not cause any problems to the car because the voltage of the car is 12V, and it will not cause harm to the human body. It is worth noting that the ground wire and battery should not be in contact with the vehicle when starting. Make sure that all electrical equipment in the vehicle without power is turned off, because the electrical equipment will drag the engine to start and increase the starting current. Let the car start quietly. If it still cannot fire, the speed of the electric car will be increased and then it will pass the normal electric car. Don't rush to disconnect the ground wire first. After the fire breaks out, let both vehicles idle the engines for a period of time to charge the batteries.
The car connection line runs through the entire car. It connects various electrical equipment on the car. As a medium for equipment power supply and signal data transmission, the main content introduces the component analysis and important role of the car connection line. It is often compared to the car nerve. Network management system, car connection line is the network economic main body of the car circuit. It connects various electrical appliances on the car and serves as the power supply and signal transmission medium for teaching equipment. Automobile connecting wires are often compared to automobile neural information network management systems, which are the network economic main body of automobile electronic circuits. There are no automobile control circuits without connecting wires.
Automotive lighting systems generally consist of headlights, exterior lights, taillights, license plate lights, instrument lights, interior lights, etc. The headlights are divided into high beam and low beam, and are controlled by a dimmer switch. The lighting is controlled by a light switch. The light switch is turned off in the 0th gear, the 1st gear is not dimmed and the lights are on (including the indicator lights, taillights, instrument lights, license plate lights), and the 2nd gear is the headlights and the dimming lights are on at the same time. The current in a lighting system generally comes from the positive terminal of the battery and is not controlled by the ignition switch. (Due to the high power of the headlight, the switch is usually switched by a light relay, and the second gear of the switch is used to control the relay coil). The super-bright signal is represented by high-beam flashing. The high-beam flashing is not transmitted through the light switch. This method is used in short Open button within time.
