How to Jump-Start a Car


It happens to all of our Bonham customers at one point or another. You park your car and leave the headlights on, causing your car’s battery to die a slow, agonizing death. That’s ok; you’ll jump start it. But there’s a problem. You don’t know how to jump-start a car battery! You could just call a jump start car service like AAA. But if you don’t want to wait an hour so, you could just read our handy guide below on the proper way to jump-start a car. OurService Team at Bonham Chrysler Dodge Jeep Ram wants you to be safe on McKinney roads. So, let’s talk about how to properly jump-start a car, and discuss what happens when your car won’t jump start.

How to Properly Jump Start a Car

We’ve found that a lot of folks in the greater Sherman area who think they know how to jump-start a car battery but don’t know the proper way to jump-start a car. So, make sure to follow the steps in this guide on how to properly jump start a car. Service may need to be scheduled if you continue to have problems after following the steps below.

  • 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.
  • Turn both vehicles off.
  • 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.
  • Connect one end of the black cable to the negative post (-) of the good battery.
  • The other end of the black cable should be attached to the metal frame of the car.
  • Start the engine of the working car and let it run a minute or two before trying to start the other car.
  • If the other car doesn’t start, let it charge for a little longer.
  • Once the car has started, remove the clamps, beginning with the black cable, then the red.
  • Allow the jump-started vehicle to run for a few minutes and take it for a short drive, which will allow for the alternator to charge the battery further.

My Car Won’t Jump Start, Now What?

If you’ve followed all of the steps correctly to jump-start a car, and it still won’t start, there are still things you can do before calling a jump start car service. Here are some things that may be the case if your car won’t jump-start:

  • The jumper cables may be loose. Make sure they are well-connected.
  • The posts or terminals may be corroded. Clean them thoroughly.
  • The starter may be broken. If this is the case, you should hear a clicking noise.
  • The battery may have reached the end of its life.
