the jump start cable will be red n black in colour, u need another car/battery to jump start your car.
Start the engine of opponent's car. (make sure the opponent's car battery is working good)
1) put the one side head of black cable at the opponent's car battery at minus terminal.
2) put another side head of black cable at your car's battery minus terminal.
3) put the one side head of red cable at the opponent's car battery at positive terminal.
4) put another side head of red cable at your car's battery positive terminal.
And then, crank/start your engine. IF your engine won't start, just let the battery charging from opponent's car. You may go have a tea break. After 10minutes, return to your car and crank/start your engine.
IF you still can't start your engine, buy a new battery and replace it.
P/S: if you needed to jump start your engine, your battery life is almost at the end. It's time to change..lolz..
