Where do you put negative jump lead?
Take the black lead and connect one end to the boosting battery’s negative terminal. The black lead’s other end should be connected to a metal bracket or bolt on the engine block of the car with the flat battery. The lead must be a good distance from the battery.
What happens if you connect jump leads the wrong way?
When the jumper cables are incorrectly connected, the polarity of the electrical system on the vehicle with the dead battery will be reversed for a few seconds. This can irreparably damage many of the sensitive electronic components that are common on today’s vehicles, such as on-board computers and electronic sensors.
What happens if you put a car battery on the wrong way?
When a car battery is connected backward, a fuse designed to protect vehicle electronics should blow. If your vehicle doesn’t have a fuse (almost all cars do) designed for this purpose, you will send electrical current backward through systems in your car, including ECU, transmission control unit, and more.
What happens when you connect the battery the wrong way?
Connecting them the wrong way may cause damage onto the battery you want to charge. For one, this causes a reverse in the polarity of the car battery. The battery may get damaged such that it will be unable to hold charge, meaning that you will have to buy a new battery altogether for your car.
What happens if you jump start wrong?
If you don’t connect the jumper cables to your car and the car you’re jump-starting in the right order, you could cause expensive electrical damage to your car – or even explode your battery.
What order do you remove jumper cables?
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 (don’t touch a grounded part of either car with the clamp of the positive cable).
