How to Jump Start a Car the Right Way

Jumper Cables

Most Smithtown believe they know how to properly jump start a car. But many are not aware that attempting to jump start a car without taking certain steps could result in injury or shorting out the car’s battery or electrical components. The service center at Atlantic Chevrolet wants you to be safe. So, we’ve put together the guide below on how to jump start a car battery and discuss what happens when your car won’t jump start.



How to Properly Jump Start a Car Battery

A lot of our Huntington drivers have learned the hard way that there’s a difference between knowing how to jump start a car and how to properly jump start a car battery. So, just follow the steps below on the proper way to jump start a car:

How to Jump Start a Car Battery

  1. The proper way to jump start a car begins with parking the working vehicle close enough to the disabled vehicle so that the jumper cables can comfortably reach from one battery to another.
  2. Turn both vehicles off.
  3. Clamp one end of the red cable to the positive (+) post on the dead battery, then connect the other end to the positive post on the good battery.
  4. Connect one end of the black cable to the negative post (-) of the good battery.
  5. The other end of the black cable should be attached to the metal frame of the car.
  6. Start the engine of the working car, and let it run for a minute or two.
  7. Try starting the car with the dead battery.
  8. Once the car has started, remove the clamps, beginning with the black cable, then the red.
  9. Allow the jump-started vehicle to run for a few minutes, and take it for a short drive, which will allow the alternator to charge the battery further.

What to Do if the Car Won’t Jump Start

Sometimes a car won’t jump start, even after following all the steps outlined above. That doesn’t necessarily mean that your battery is completely dead and needs to be replaced. Here are some things that may be the case if your car won’t jump start:

  1. The jumper cables may be loose. Make sure they are well-connected.
  2. The posts or terminals may be corroded. Clean them thoroughly.
  3. The starter may be broken. If this is the case, you should hear a clicking noise.
  4. The battery may have reached the end of its life.
  5. If none of the above works, schedule a service appointment with us online.
