The car battery connection sequence, the battery connection sequence diagram

In the process of starting the car, the sequence of connecting the battery cables is a very important process, otherwise the connection error is likely to cause serious consequences.

Diagram of the sequence of battery charging:

1. The car needs a rescue vehicle that can be powered by the battery. The front of the car should be leaned together. Note that whether it is a rescue vehicle or a rescued vehicle, the operation of the battery must be carried out in the flameout state;

2. Open the engine compartment cover. If the battery has a protective cover, you need to remove the protective cover to expose the positive and negative poles of the battery. Note that you must distinguish the positive and negative poles of the battery. If you can't tell, you must not start to connect;

3. Take a connecting wire and connect one end to the positive electrode of the dead battery and the other end to the positive electrode of the battery. Note that the positive and negative poles should not be in contact, otherwise a short circuit will cause danger;

4. Take another connecting wire, one end is connected to the negative electrode of the battery, and the other end is connected to the negative electrode of the battery or the car body;

5. After the connection line is set up, start the electric rescue vehicle, so that the ignition voltage can be provided to the vehicle with no battery;

6. Finally, remove the connecting wire, first remove the positive electrode of the rescue vehicle, then remove the positive electrode of the rescued vehicle, then remove the negative electrode of the rescue vehicle, and finally remove the negative electrode of the rescued vehicle.

Precautions for the car to take the battery:

1. When the battery is out of power, you can't continuously try to ignite, which will only make the battery with insufficient power to use up the last "surplus".

2. It must be carried out in accordance with the above battery connection sequence, otherwise it is likely to cause a short circuit.

3. The wiring should be from one end of a connecting wire to the other, and then another connecting wire, also when disassembling.
