Never connect the black cable to the negative (–) terminal on your dead battery. This is very dangerous, could result in a possible explosion. Make sure you follow the instructions in your owner's manual when jumpstarting your vehicle.

You may wonder, can you do negative to negative when jumping a car? Connect Negative to Negative:

Connect the negative (often black) clamps of the jumper cable to the negative terminal of the live battery. In your car, stick the negative terminal to an unpainted metal surface.

Similarly one may ask, do you have to connect the negative jumper cables? Don't attach the negative (black) clamp to the negative terminal of the dead battery. 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.

Besides above, where does the negative go when jumping a car? One is marked positive (+), the other negative (-). There are also positive and negative cables in the jumper cable set. The red one is positive (+), the black one is negative (-). Never connect the red cable to the negative battery terminal or a vehicle with a dead battery.

Likewise, why do you connect positive 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.


What happens if you connect positive to negative on a battery?

If the positives and negatives are switched, the battery will try to compensate and make the negative 12 volts into a positive charge resulting in a huge surge of power and an enormous amount of heat to be produced.

Can you jump a car with just the positive?

Never use damaged jumper cables, always hook them up while the cars are off, and take care to ensure proper connection to the correct terminal (positive or negative). Always use both terminals of the good battery but only connect the jumper cable to the positive terminal of the bad battery.

    Can you connect negative to any metal?
