Positive And Negative Car Battery Terminals

The red one is positive the black one is negative.

Positive and negative car battery terminals. 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. A negative terminal is the grounded terminal on a car battery typically marked by a minus sign. I am assuming you are referring to installing a battery not performing a jump start.

Here s how it s done. One is marked positive the other negative. There are also positive and negative cables in the jumper cable set. The grounded terminal connects to a grounded source on the vehicle.

The negative terminal of a battery is connected to the chassis of the car and as a consequence it is grounded.

Each battery has two metal terminals. 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.

That is why the negative terminal is called the ground terminal. 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. Find the batteries and their terminals. When disconnecting a battery the negative terminal is disconnected first to cut off the circuit and avoid a short.

The other terminal is positive usually color coded red or orange and marked with a plus sign. 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. It is only a safety issue. It is usually color coded black.

And of course always reconnect the ground last.
