How to Jump Start a Dead Car 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!
- 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.
- 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.
- Next, attach the negative (black) cable to the live battery’s negative terminal.
- 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.
- 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.
- Start the car with the dead battery. If it doesn’t start, let it sit for a few more minutes and try again.
- 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.
