A) to attach the positive cable to the negative terminal of the dead battery
B) to attach the negative cable to the positive terminal of the dead battery
C) to attach the negative cable to a metal part of the car’s engine block
D) to attach the positive cable to the positive terminal of the dead battery
Answer:
The correct option is D) to attach the positive cable to the positive terminal of the dead battery.
When jump-starting a car, it is important to connect the jumper cables correctly to avoid damaging the vehicles and causing injury. The correct sequence of steps is as follows:
- Park the donor car close enough to the recipient car so that the jumper cables can reach both batteries.
- Turn off the ignition and all electrical components in both cars, including lights and radios.
- Attach the positive (red) jumper cable to the positive terminal of the dead battery.
- Attach the other end of the positive (red) cable to the positive terminal of the donor battery.
- Attach the negative (black) jumper cable to the negative terminal of the donor battery.
- Attach the other end of the negative (black) cable to an unpainted metal surface on the engine block of the recipient car, away from the battery and fuel system.
- Start the donor car and let it run for a few minutes to charge the dead battery.
- Attempt to start the recipient car. If it starts, let both cars run for a few minutes before disconnecting the cables.
- Disconnect the jumper cables in the reverse order, like a negative cable from the recipient car, negative cable from the donor car, positive cable from the donor car, and finally positive cable from the recipient car.
