How to use Jumper Cables
If you keep only one tool in your vehicle at all times, keep a set of jumper cables. Jumper cables allow you to get your vehicle started in the event that the battery dies. If you have a set with you, you can ask someone to give you a jump and get your car running again. Almost everyone will be faced with this kind of situation at least once in their life. Whether you have an inconsistent battery or electrical system or you simply left your headlights on, jumper cables can get you out of jam.
Jumper Cable Use
Find a person willing to let you use their car battery to jumpstart your car and have them pull up to your vehicle nose to nose if possible, otherwise along side of you. With their car running, attach the red clamp to the positive terminal of your battery and the corresponding red clamp to the positive terminal of their car’s battery. Next, attach the black clamp to the negative terminal of your battery and the other black clamp to the negative terminal on their battery. You can also attach the second black clamp to a piece of grounded, structural metal on the running car to protect their battery from a surge.
Once connected, turn the ignition over in your car until it starts. After your car is running, disconnect the battery cables in the reverse order that you connected them. Jumper cables are a big help and can mean the difference between getting back on the road and getting stranded somewhere.
