It’s bound to happen to you or someone you know. The aggravating sound of your car attempting to start, but falling just short (or the aggravating sound of your friend calling you to drive 50 miles to help them jump start their car). Even though it’s a pretty common occurrence, jump starting a car is not the easiest of tasks if you don’t know what you’re doing. So to help you learn what to do, we put together this blog with instructions for jump starting a car.
To get started, line up both cars so that the batteries are as close as possible. Make sure both cars are off (one should already be off due to the whole dead battery predicament) and not touching each other. Headlights, blinkers, radios, and A/C should all be off. Unplug anything such as cell phones, GPS, or radar detectors. Jump starting a car sends 300+ volts through your car and could damage anything that is plugged in.
If the battery is cracked and liquid is leaking, do not proceed! If it’s defected or broken in any way, it’s time to buy a new battery. If you try to jump start a cracked/leaking battery, it could explode. If the battery is in good condition, try to clean off any corrosion that might be found around the dead battery’s terminals.
Now we’ll move onto connecting the cables. The positive cable is usually red/orange and the negative cable is usually black, but check to be sure. Your battery’s positive and negative terminals should be clearly marked:
- Attach the end of the positive (+) cable to the positive (+) post of the dead battery.
- Connect the other end of the positive (+) cable to the positive (+) post of the good battery.
- Connect one end of the negative (-) cable to the negative (-) post of the good battery.
- Attach the other end of the negative (-) cable to a good shiny, non-painted metal part of the engine on the dead car (most metal bolts/nuts will do as long as they are not attached to the battery). When you attach this cable (referred to as ‘Grounding’) you’ll get a normal spark as the circuit is completed.
- Now that your cables are attached, it’s time to start the engines. Turn on the car with the good battery and leave it running. Turn the key in the dead car and it should start right up! In newer models with key immobilizers, you have to turn the key to the “run” position for 30 seconds before trying to start the car.
It’s important to follow these steps exactly. Doing them in a different order could potentially cause unwanted sparking.
You can disconnect the jumper cables right away. Disconnecting the cables should be done in the reverse order of how you attached them. Don’t let the black & red cables touch each other at the end when they are still connected to one battery. You also want to avoid laying cables over fans or belt areas.
Make sure you memorize these steps and use caution so that the next time you (or that pesky friend) tries to jump start a dead car, you’ll know what to do. If you’re a visual learner, you can check out the video below that follows the same steps to jump a car. Any vehicle service contract holders should contact their Roadside Assistance Providers, as they will be able to send a technician to provided the needed jump start. This is just one of the many benefits of being a vehicle service contract owner.
