First you have to have a battery cable and a car with electricity, and then put the two cars close enough that the battery cable can reach the batteries of the two cars. If the battery has a lid, take the lid off first, and then start to connect, remember that the direction is positive to positive, negative to negative, that is, let the two batteries in parallel. This must not be reversed, the reverse is to let the two batteries short circuit, the instantaneous current is too large, may burn the battery, may also burn the electronic parts of the car.

When connecting, it is necessary to operate one wire one wire, not two wires at the same time. First connect the positive terminals of the two cars, after the positive terminals of the two cars are connected, and then connect the negative terminals of the two cars. The order of connection is not required, either with or without trams can be connected first. It should be noted here that some battery negative electrode is hidden inside, it is not easy to use the battery clamp, then it is possible to find the metal part of the body connection, because any metal part of the car body is connected with the negative electrode of the battery, it can be seen as the body is the negative electrode, but to find a good electric metal part.

Once they're all connected, the powered car stays on fire, and then starts the dead car. The battery line can be removed after the fire, but also to be removed one by one, can not remove the two lines on a battery at the same time, in case of accidentally short circuit. First remove the negative connection wire of the two cars, and finally remove the positive connection wire.

This process may encounter problems: the battery connection line is connected, but the car without electricity can not start, start no reaction. There are two possible reasons for this, one is that the battery connection line is not connected, there is no current to the car without electricity; The second is that the car battery with no electricity is too serious, and the current coming is not enough to drive the starter. How do I know if the battery is connected? When the last battery wire clamp to the negative electrode, see if there is an electric spark, if there is an electric spark, indicating that the battery wire is well connected. If there is no spark, it means that the battery line is not connected well, and the place where it is connected may have rust leading to poor contact, change a place to reconnect. After the battery line is connected, it can not start, that is the second situation, the battery loss is too serious, this situation only needs to wait a few minutes and then the flame can be. Let the car with electricity charge the car with electricity loss for a while, three or five minutes can be played, and then you can play the fire.

Learned how to take the electric, then can not fire how to know the car is out of electricity? There are many people who will not judge, turn on the headlight to see that it is bright, press the horn also rings, and say that the battery has electricity, not the battery problem. You know, the battery has very little electricity, you can make the lights, the horn, but to drive the starter, you need to have enough electricity. At the moment of starting, the current is very large, and the demand for electricity is very large. Measured with a voltmeter, the battery voltage is less than 11 volts, and the starter cannot be operated and the fire cannot be hit. Therefore, to judge the battery is out of power, a voltmeter is 100% accurate. Ordinary owners will not have a voltmeter how to judge, listen to the sound of the starter when starting, if you hear a crack, no sound, indicating that the battery is out of power. If you hear the clap has been ringing, but with the normal starting sound
The correct way to charge a battery
A car with electricity will drive next to the car in the five shops, and the front should be relatively close to it.
Two Open the covers of both cars and take out the charging clips.
Three Find the battery of the two vehicles, and connect the positive electrode to the positive electrode and the negative electrode.
Four start the car with electricity charge a few minutes after the start of the car without electricity can be started.
The car should not be put for too long, and it is best to start for a few minutes every half month to avoid battery loss.
If the car can not start, it must be the battery loss, the correct way to build should be:
First, open the positive line above the car battery.
The second is to disassemble the negative electrode line on the car battery.
The third is to clamp the positive electrode of the electric battery and the positive electrode of the car with the lap wire, and then clamp the negative electrode of the electric battery and the car girder with the lap wire respectively to start the car.
