Question: Do you put red or black jumper cable on first?

Attach the red jumper cables first. Start by clamping one red cable to the positive side of the battery that wont 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.

When jumping a car which cable goes on first?

Disconnect the cables in the reverse order: First remove the negative cable from the car you jumped, then the negative cable from the car with the good battery. Then remove the positive cable from the car with the good battery (dont touch a grounded part of either car with the clamp of the positive cable).

Does the order of jumper cables matter?

It is important to connect the cables in that order, and it is safest to connect the negative (black) clamp as far from the battery as possible, in order to reduce the risk of sparking that could cause a fire or explosion.

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

Hooking the jumper cables up backwards can create disastrous results⁠. Possible outcomes include irreparable damage to the battery, fried electronics, and even serious personal injury. You might cause personal injury and/or damage to your car if you accidentally hook your jumper cables up wrong.

What happens if you mix up jumper cables?

What happens if you touch jumper cables together? When the jumper cables are hooked up to a battery, touching the cable ends together can create sparks. In some cases, the sparks can ignite the hydrogen gas escaping from the battery, causing an explosion.

What happens if you disconnect positive first?

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