Proper use of jumper battery cables

First, open the protective cover of the battery, and then connect the red end of the live wire to clamp the positive part of the battery. At this time, the positive pole is connected to the positive pole.

Make sure that the red wire connector does not touch the negative electrode of the battery and the metal parts of the body to prevent a short circuit, which will cause the batteries of the two vehicles to be destroyed.

Connect the black wire to the negative terminal of the no tram.

Connect the other end of the black wire to the negative pole of the electric car battery. Note that you cannot connect the black wire first and then the red wire. You must first connect the red wire and then the black wire to prevent short circuit and damage the battery.

Start the trolley, idle for a while, and properly charge the battery of the trolley.

Be sure to turn off all electrical equipment without electric car, because the electrical equipment in the car will start the engine, so that the current required for starting is larger.

 If you still can't start the fire, turn up the speed of the tram. Don't be in a hurry to take off the live wire. Let the engines of the two cars idle for a while to charge the battery.

Wait until the no tram starts up normally, you can take down the live wire. The sequence of removing the ignition wire is to first remove the positive pole of the trolley, then remove the positive pole of the non-tram, first remove the negative pole of the trolley, and then remove the negative pole of the non-tram.

Be careful not to mistake the positive and negative poles of the ignition wire. Do not touch the ignition wire and car battery at the moment when the vehicle is started, so as not to hurt the human body.
