How to Jump-Start Another Car

Once you understand a few basic points, and with some practice, you can jump start another vehicle. The first thing to realize is that each end of the jumper cables has a positive and a negative charge. The positive is indicated in red and the negative charge is in black. Be aware that once you begin connecting the cables to one of the batteries, you should use care not to touch the others to a metal surface.

Start with the positive cable on the dead battery. Connect it to the battery’s terminal that’s marked with a plus sign. Go on to the negative cable and connect it to the terminal that’s marked with a negative sign. Repeat the process with the good battery. Leave the car with the good battery running for a couple of minutes to build a charge. Rev the engine and try to start the car. It should start within a few tries. If it’s not starting, you should stop and have your vehicle serviced.
