What is the correct way to hook up jumper cables?

Connect one red clamp to the positive (+) battery post of the “dead” battery. Connect the other red clamp to the positive (+) post of the good battery. Connect one black-end clamp to the negative (-) post of the good battery.

Which battery terminal do you connect first when jumping?

“Positive first, then negative. When disconnecting the cables from the old battery, disconnect the negative first, then the positive. Connect the new battery in the reverse order, positive then negative.”

How do you connect terminals to jump start?

How to jump-start a car steps:

1. Clamp the positive (red or yellow) cable to the positive terminal of the weak battery.
2. Clamp the other end of the positive cable to the positive terminal of the good battery.
3. Clamp the negative cable (black) to the negative terminal of the good battery.

How do you use jumper cables to start a dead car?

Turn off the ignition on both cars. First, clamp one end of the positive cable to the dead battery’s positive clamp. Now have a helper connect the other end of that cable to the other battery’s positive clamp. Next, connect the negative cable to the negative terminal on the good battery.

When jumping a car which cable do you ground?

The positive (red) cable should be attached to the positive terminals on each battery. The negative (black) cable should have one end attached to the negative terminal of the dead battery, and one end grounded.

How do you jump a dead battery with jumper cables?
