How to jumpstart a car with cables youtube

Attach one red jumper cable clamp to the positive terminal on the dead battery. Attach the other end of the same cable, the second red jumper cable clamp, to the positive terminal on the working (live) car battery. Attach one black jumper cable clamp to the negative terminal of the working (live) car's battery.

Step 10: Disconnect the black jumper cables first, then disconnect the red ones. Once the dead car is running, you may disconnect the jumper cables, starting with the black, negative cable clamps. Do not let the clamps touch each other while any part of the cables is still attached to a car.

The only method to start an automatic car with a dead battery is to use a portable battery charger. If you drive an automatic car, make sure you have a simple portable charger in your roadside emergency toolkit.

Never connect the black cable to the negative (–) terminal on your dead battery. This is very dangerous, could result in a possible explosion. Make sure you follow the instructions in your owner's manual when jumpstarting your vehicle.
