Jump Start a Dead Battery

Read below on how to jump start your dead battery!

Do you know what to do if you or someone you know has a dead car battery? If your answer involved calling roadside assistance, you don’t. The truth is you can jump start a car quickly and, if done right, you’ll be on your way before roadside assistance even hits the road. We here at Crossroads Automotive can explain how to jump start a dead car battery in only a few steps!

  1. Identify the terminals and jumper cables. The red terminals on the battery are positive and the black are negative. The same goes for most jumper cable sets.
  2. Once you’ve identified the terminals, attach the positive (red) cable to the dead battery. Attach the other end to the positive terminal of the live battery.
  3. Next, attach the negative (black) cable to the live battery’s negative terminal.
  4. Attach the other end of the negative cable to a piece of unpainted metal under the hood. Jumping posts are there for this purpose. If you can’t find a jumping post, an unpainted bolt will do just fine.
  5. Once the cables are secure, start the engine of the car with the live battery. Let it idle for a few minutes and rev the engine lightly.
  6. Start the car with the dead battery. If it doesn’t start, let it sit for a few more minutes and try again.
  7. Once both cars are running, let them idle for a few minutes before disconnecting the cables. To disconnect the cables, remove them in the opposite order you attached them.
