Why should you Jump Start a car?

Your battery helps in initiating the ignition process in the engine. The motor receives electric current as soon as you turn on the engine. This allows the motor to move the car’s flywheel and consequently starts the crankshaft rotations. This further results in a compression stroke, and after that, spark plugs complete the rest of the process.

Nevertheless, if this explanation is too complex for you, let’s put it in a much simpler way.

A battery is the power source that helps the motor to start the car. It does so by supplying high electric current. Now, when you have drained out the battery by overusing, it won’t be able to supply the electric current to the motor. Consequently, the motor won’t be able to give the push required to start the vehicle. This is the situation where your car will need that push externally by Jump Starting.

Car batteries come with two large screw-like points called terminals. One is positive, and the other is negative. Both of these terminals will be marked very clearly. You must connect the jumper cables to the right terminal as it provides the power to recharge the battery.

Positive terminal – The two bigger terminals are mostly positive and are marked by POS or a + sign. You will connect it to the positive red clip on the jumper cable.

Things to do before you start

  • Pull your cars near each other so that you can connect the cable. However, do not let the two cars touch How to Jump-start your Car in 2020each other to prevent a short circuit.
  • Turn off the ignition, lights, and any other accessory in both the cars before you start with the process. Also, make sure that both cars are either neutral or in the park position. Don’t forget to put on the parking brake.
  • It is best to keep your eyes safe with safety glasses.
  • Never smoke near the area. Even a minor spark can induce an explosion.
  • Frozen batteries tend to explode if you try to jump-start them. So, never try to jump if your battery is frozen. If you see, one or more battery sides will seem to bulge out, which is a sign that your battery is frozen.
  • Ensure that you have correctly identified the positive and the negative terminal of the batteries to know the correct position where you need to place the jumper cables.
  • Make sure that you have enough space to do the clamping.
  • The positive terminal is usually connected to your vehicle’s charging or starting system. You will see a red cable with a plus sign. The negative should be connected to the engine of the car and is denoted by a minus sign.

Once you have identified all the right terminals and have prepared yourself with all the precautions, let’s start with a jump-start. Follow the step below –

  • Clamp the red or yellow wire (positive) to the battery’s positive terminal that you want to jump-start.
  • Ensure that the other end does not of the cable does not get in contact with any of the car’s engine or your body. The cable can induce a dangerous spark if it gets in contact with the car or your body.
  • Now clamp the other terminal of the positive cable to the positive end of the battery.
  • Clamp the black negative cable to the negative terminal of the battery that is in good condition.
  • Clamp the other side of the negative wire to clean the metal (bracket or bolt) of the vehicle’s engine. Don’t let the clamp touch the battery or fuel system that can cause an explosion.
  • Warning – Don’t connect the negative wire to the negative terminal of the weak battery. It can result in the ignition of the hydrogen gas instead of the battery and lead to a massive explosion.

  • Once the car with the drained battery starts, wait for around 15 seconds to ensure that it does not stop again.
  • Now, disconnect the wires in the opposite order – first, disconnect the negative wire from the vehicle you jump-started, and then the negative wire from the car used to charge the battery. Then disconnect the positive wire from the supporting car. Ensure that you are not touching any of the grounded parts of both How to Jump-start your Car in 2020the cars with the clamp of the positive wire. The final step would be to remove the positive wire from the vehicle with the weak battery. Don’t let cables touch any part of the car’s moving parts as both the engines are running at this point.
  • If you are living in a cold climate area, choose the thickest gauge cable. The lower is the number of the cable, the thicker it will be.

Note – If the car does not start even after all the attempts, you should consider that it is far too drained to jump-start.
