Need a jump?

Q: How do I jump start my car? – Mrs. Rosenburg

 

A: Mrs. Rosenburg, 

In an emergency, it might be necessary to jump start your car.  You need a decent set of jumper cables – heavy wire; no frayed or worn insulation; clean, strong clamps tightly connected to the cable ends. As you connect the cables, do not allow the ends to touch. Follow these steps:

1 – Park the booster car as close as possible to the disabled car without the two vehicles touching.

2 – Clamp one end of the positive cable (red) to the positive terminal (+) of the dead battery.

3 – Connect the other end of the positive cable to the positive terminal of the booster battery.

4 – Connect the negative cable (black) to the negative terminal (-) of the booster battery.

5 – Clamp the other end to an unpainted ground on the disabled car such as a bolt or bracket in the engine compartment. Do NOT clamp to the negative terminal of the battery.

6 – Check your cable/terminal connections: positive to positive on both vehicles, negative to negative on the booster car, and clamp the negative cable to an unpainted ground away from the battery on the disabled vehicle.

7 – Start the booster car and allow it to idle for a few minutes. Do not rev the engine.

8 – Attempt to start the disabled car.

9 – If the car does not start, let the booster car idle for a few more minutes and repeat.

Please note: jump starting your car poses a potential (but small) risk of explosion of the hydrogen gas that can build up in lead-acid batteries, as well as potential damage to vehicle electrical components. Keep bystanders away. Stand clear of the batteries except while making connections.
