How long should you wait to turn off the engine after jump-starting a car?
1 Answers
You can turn off the engine about half an hour after jump-starting the car. Detailed steps for jump-starting a car: 1. Take one jumper cable and connect one end to the positive terminal of the rescue car's battery, then connect the other end to the positive terminal of the rescued car's battery. 2. Take another jumper cable and connect one end to the negative terminal of the rescue car's battery, then connect the other end to an unpainted metal surface on the rescued car's engine. 3. Start the rescue car first, then start the rescued car following the normal procedure. 4. After the rescued car starts successfully, let it idle for about half an hour to charge the battery. Important notes: When connecting the cables, always connect the positive terminal first, then the negative; when disconnecting, always remove the negative cable first, then the positive.
