What order do you put the cables on when jumping a car?

Attach the red jumper cables first. Start by clamping one red cable to the positive side of the battery that won’t start. Then attach the other red clamp to the positive side of the working battery. Next, clamp one black cable to the negative side of the working battery.

Which battery terminal do you connect first when jumping?

Safety First: Remember, when connecting the positive cables to the batteries, you should always start by connecting the dead battery first. If you feed energy into the cables before they are connected to your battery, you can cause a safety hazard.

When jumping a car where do you put the negative?

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 jumpstart a car battery What is the first step?

Common Steps to Jump-Start a Car 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.

Why do you connect the positive terminal first?

Connect positive first, negative having less potential won’t arc. The higher the voltage, the greater the chance of arcing and fusion. On a car if negative first and you are touching any metal part of car, when attaching positive there is possibility of arcing through you. Your body becomes part of the circuit.

Do you put the positive or negative terminal on First?

“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.”

Why do you ground a terminal when jumping a car?

The reason for connecting the negative cable to ground rather than to the negative terminal of the dead battery is to minimize the chances of a spark near the battery, where there may be potentially explosive gasses.

What happens if you connect jumper cables in the wrong order?

Fuses (and/or fusible links) act as circuit protection devices between the battery and the vehicle’s electrical system. Connecting the jumper cables backwards will often result in one or more blown fuses. The affected circuit will not function correctly until the blown fuse is replaced.

Why do you remove the negative terminal first?

Negative first It’s important to disconnect the negative side of the battery first, otherwise you can cause an electrical short if the positive is removed first.

Do you take the red or black cable off first?

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.”
