Step by step instructions for jump-starting a car with a dead battery
A dead car battery is one of the most common problems people face with cars. Car batteries could go dead for a number of reasons, ranging from aging batteries to forgetting to turn the lights off in the car draining the battery.
One of the easiest fixes for a dead battery in older cars with manual transmissions was a push start. But that’s not recommended for modern cars and automatics, and the conditions may not always be viable for a push start.
One of the most-handy emergency tools to carry with you in the car always is a pair of jumper cables. They cost about Rs. 500 for a good set with strong crocodile clips, and are available at auto accessories shops.
They could get you out of trouble on a cold day when your car battery just decides to die on you or they could earn you some good “Carma” by helping out someone else in trouble.
Here’s how you go about jump-starting a car with a dead battery. You will need a car with a healthy battery nearby to act as the donor car in the jump start.
Check the car with the dead battery. One of the sure signs of a dead battery is if the warning lights appear on the dashboard when you turn on the ignition, but the car refuses to crank or cranks very slowly when you turn the key.
Line up the donor car with the car that has the dead battery and open the hoods of both cars.
Start the engine of the healthy car.
Connect the Red jumper cable to the Positive (+ sign) terminal of the battery in the Dead car. Make sure the other end of the jumper does not touch any part of the car.
Connect the other end of the Red jumper cable to the Positive (+ sign) terminal of the battery in the Healthy car.
Connect the Black jumper cable to the Negative (- sign) terminal of the battery in the Healthy car.
Connect the other end of the Black jumper cable to a good grounding point or unpainted area like an engine bolt or bonnet latch – a point away from the battery on the Dead car. The reason this is done is because the moment you connect this cable you will see some sparking. Batteries usually give off hydrogen gas and a spark just over the battery can sometimes cause a fire.
Switch on the ignition of the Dead car. You will see the warning lights all appear brighter. Start the car, and it should fire to life. Keep the engine running.
Disconnect the cables in reverse order, starting by removing the negative jumper cable on the revived car, then on the donor car. Then remove the positive jumper cables making sure they don’t come in contact with the body of the car.
Shut the hood of the revived car, but leave the engine running or take it for a drive for at least 10-15 minutes to ensure the battery charges enough to start the car on its own again.
