Positive And Negative Car Battery Terminals

If you first connect the negative cable then when you connect the positive cable there is a chance the wrench will complete a circuit.

Positive and negative car battery terminals.

The negative terminal of a battery is connected to the chassis of the car and as a consequence it is grounded. Jump starting a vehicle with a set of jumper cables is pretty easy. Never connect the red cable to the negative battery terminal or a vehicle with a dead. That is why the negative terminal is called the ground terminal.

The good battery should have the positive jumper cable attached to the positive battery terminal and the negative jumper cable attached to the negative battery terminal.

While car batteries technically have the amperage to kill you the voltage is a different story. One is marked positive the other negative. And of course always reconnect the ground last. The other terminal is positive usually color coded red or orange and marked with a plus sign.

Subsequent shorting of the positive terminal to ground will then produce no current flow because the current has no return path to the negative post. When disconnecting a battery the negative terminal is disconnected first to cut off the circuit and avoid a short. I am assuming you are referring to installing a battery not performing a jump start. It is usually color coded black.

The grounded terminal connects to a grounded source on the vehicle. It is only a safety issue. Find the batteries and their terminals. There are also positive and negative cables in the jumper cable set.

The math can get a little complicated but the main reason that you can safely touch the positive and negative terminals of a typical car battery and walk away unscathed has to do with the voltage of the battery.
