Getting into your car to find that it won’t start is never a good start to the day. But, if your car battery does ever go flat on you, it may be a lot easier to fix it than you think.
Using jump cables, you can re-start your car with a high-voltage shock, which will get it going just enough to start re-charging the battery.
For this, you’re going to need an extra pair of hands, and an extra four wheels. The power from the other car will work to charge yours. Be sure to double check that neither vehicle is equipped with an electronic cut-off system or is an alternatively fuelled vehicle as the use of jump cables could potentially cause further damage.
Ensure that both vehicles are parked up in neutral with the hand brakes on and the engines off. Attach one of the red clips to the positive terminal of your battery – it will have either a POS, have a plus symbol on it or be much bigger than the negative terminal.
Attach the other red clip to the positive terminal of the other car. Then attach one of the black clips to the negative terminal on the other car battery. Attach the last clip to the negative terminal of your car battery.
Turn on the engine for the working vehicle and let the engine run for a couple of minutes. After that, try to start your car.
If after a few tries the jump eventually works and your car starts to run, then be sure not to switch off your engine. Drive around for at least 15 minutes to ensure that sufficient power is generated.
Although this process is designed to get your car back up and running, it’s worth noting that we wouldn’t recommend this very often and that if the problem persists you should take your vehicle to your nearest garage to be checked.
