Every person likes to own a car. But, the real game is learning all the crucial techniques like how to use jumper cables, how to change tires,  how to clean the engine bay and so on.

Let’s assume that you are out to run an errand and suddenly your car won’t start. Trust me sometimes it’s better to take matters to your hand than waiting for someone to come and save you. So, from this article, I’m going to guide you on how to use jumper cables to jump start your car.

If you drive a vehicle, it’s better to have a sound knowledge regarding every part of your car. Let’s say your vehicle stalled nowhere, and what would you do? If you can check what’s wrong with your car and fix it by yourself, you are saving a lot of things. You are saving your money and also your time. So, rather than expecting everything from a mechanic, try to learn handling situations on your own.  

First, let’s learn what a jump start is.

Jump start simply means using another vehicle’s battery to recharge ( or give a temporary boost) the dead battery of your car which will help you to start it

But how can I know whether my car’s battery is dead or not?

Easy. When you turn the ignition on, your car won’t start. So, if your vehicle does nothing even after you turned the key,  or give out a very weak cranking sound the problem is most probably with the battery.

But, if you hear the normal cranking sound from the engine when you try to ignite your car, trust me that’s not a problem with the battery.

So before learning how to use jumper cables, let’s gather the supplies we need for the process.

  • Jumper cables
  • First aid kit
  • Flashlight
  • A screwdriver
  • Jump start power pack ( if there’s no car passing by, you have to use the jump start power pack as a power bank to recharge your car’s battery)

Right, now let’s get into the business.

There are  few conditions you have to verify before learning how to use jumper cables to recharge your car.

Read the manual to have a better understanding of your car. You need to check the details of your vehicle before learning how to use jumper cables.  

  • Make sure that both batteries in the two vehicles are similar in voltage. If not, it can burn the electrical components in both cars.
  • Keep the two vehicles close to each other as much as possible.  But DO NOT park them in a position to touch with each other.
  • Make sure both cars are turned off, and the vehicle is in Park or Neutral gear.
  • Use the parking brake in both vehicles.

Now it’s time to attach the terminals for the batteries. Please read the guidelines carefully to avoid any potential hazard.

There’s a slight chance that you might be confused with which terminal attaches to where or like, “is red positive?”

For your ease, try to remember that the terminals are marked as red is positive and  black as negative. Some times instead of color coding you will see a (+) sign which indicates that terminal as the positive. Keeping that in your mind, let’s move to the most crucial part of the process of learning how to use jumper cables.

  • First, attach the black-end clip to the negative terminal of the working battery.
  • Then, take the other black end and connect it to the metal surface, which is in the dead-battery car engine block.

Never attach the negative cable to the dead battery because it results from having battery gases in your vehicle. And it causes sparkling which could damage the electrical components in the vehicle.

  • Take one of the red clip and attach it to the positive terminal of the dead battery.
  • Take the other end of the red clip and connect it to the positive terminal of the working battery.

Remember again , red is positive &  black is negative.

Okay, now the hardest part is done. Please, I advise you again,  make sure that you read the guidelines carefully to get familiar with how to use jumper cables.

You have done a successful job of connecting the cables. Now, let’s move to the end of the process.

First, turn the ignition of the working car and run it for a few minutes.

After that turn on the engine of the vehicle with the dead battery. When the car starts to run, remove the cables as soon as possible in the reverse order.

Remember, when the car with the dead battery started to run again, don’t turn it off. You have to ride it for a minimum of 15 minutes to recharge its battery.

Only after that, you have to take it to a garage to check the condition of the battery whether you need to replace it or not. By checking the status of the battery by an expert, you can also check the battery voltage.

If the car doesn’t start, you have to make sure the cables are correctly connected. And rerun the process.

But, if your vehicle doesn’t start, it seems like you can’t handle the situation on your own.

Let’s say that your car started after connecting the cables, but when you try to use the car again, it won’t start. So, it means that you have to replace the battery to use your vehicle again.

So, I hope you got the answer for can you jump start a car with a bad starter from the mentioned simple guidelines. And wish you good luck in not getting stranded again with a dead battery.
