Park the functioning car so that the vehicles face each other, preferably only about 18 inches apart, but never touching each other. For automatic transmission cars, put the vehicle in park; for a manual transmission, set the vehicle to neutral. Set the parking brakes on both, so neither car moves unexpectedly. Both cars should be turned off, with keys removed. Set down the jumper cables on the ground, making sure the clamps do not touch each other.
Look at the batteries and make sure that you can identify which is positive, and which is negative. This distinction is crucial to the success of your jump. If the battery terminals are dirty, wipe them off with a rag or wire brush. You want a solid connection to the battery terminal, which may require some initial wiggling of the clamps.
Walk over to the car with the dead battery. Do not connect the black, negative cable clamp to the dead battery. Instead, attach that clamp to an unpainted, metal part of the car such as a shiny, clean nut on the engine block. This will help ensure a safe jump. Start the working vehicle. Wait a minute or so. Depending on the age of the battery and how long since it died, you may need to let the car run for a minute or two to get the jump to work.
Try starting the dead car. If the car doesn't start, allow the working vehicle to charge the battery for an additional minute or two before attempting again. In some instances, slightly revving the engine of the working car while charging the dead battery may help. 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.
Now, take a short drive. This will allow the battery to build up a charge. If the jump fails to start your car after a few short attempts, or if the car starts but then dies again, you have some other issues you need to address. Most batteries are rated to last years. If your battery is old, you may need to replace it. If the battery should be working well, you should consider other possible problems with other components, including:.

From there, consider the condition of the battery itself.

What happens if you put jumper cables on the ground when the car is running?

The article is incorrect in stating that jumper cables are not usually different lengths, this is to prevent the possibility that the ends could touch together and short circuit.

How to Hook up Jumper Cables. Article Summary X To hook up jumper cables, park the donor vehicle next to the vehicle with the dead battery, turn both vehicles off, and set the parking brakes.
Did this summary help you? Tips Some vehicles have plastic covers over the entire battery you have to remove before attaching the cables. You can remove it by prying it off or unscrewing it. Take a recently-jumped car for at least a 15 minute drive to charge the battery. Some cars have batteries under the rear seat or in the trunk of the car.
These cars may also have a jump port under the hood. Clamp the red jumper cable to it after prying off the cover. Shorter cables tend to work better since the electrical current has less distance to travel. Longer cables can lead to weaker currents and increased charging times. Get a rechargeable battery pack for jump-starts without needing a working car. You keep the battery pack charged through its USB port, then hook the jumper cables to it like you would normally when you have a dead battery. Warnings Avoid jump-starting a frozen battery. If you can open the battery, look to see if the liquid inside of it has frozen.
Car batteries discharge explosive hydrogen gas, so avoid smoking near them. Also make sure the black grounding cable is not attached to the negative terminal on the dead battery. Article Info This article was co-authored by Andrew Everett. Did this article help you? Cookies make wikiHow better.
