Why do you connect the positive terminal first?
When jump starting cars always positive cable is connected first! Reason is simple, if cable drops and touches car nothing happens cause cars are still isolated – missing negative. But if negative is connected first, dropping positive will short both cars.
Do you need to connect negative when jumping a car?
That’s why it is recommended that you connect the negative jumper cable to the vehicle body and not the negative post of the battery. This is so you can avoid sparks from occurring near the battery where flammable hydrogen gas may be present, resulting in a possible explosion.

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.
How do you tell positive and negative on a car battery?
Car battery terminals will be marked and color-coded. The color red and the plus sign for the positive terminal and the color black and the minus sign for the negative terminal. The negative terminal connects to the vehicle’s metal chassis.
Which side of a battery symbol is positive?

Which car do you start first when jumping a dead battery?
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.
