Is The Black Wire Always Negative On A Car Battery

Conventional standards also declare that the black terminal of a car battery represents the negative terminal. Typically, the negative symbol is stamped or engraved on the black terminal of nearly all kinds of vehicle batteries.

In most cases, you will see a black protective cover on the terminal of the battery casing. Battery manufacturers are putting these protective covers to prevent accidental shorting of the terminals.

If there is no protective cover on your battery or it is missing, look for the mark or symbol on the terminal post itself. It is always safe to look for this symbol on the battery before connecting or disconnecting the terminal to another terminal.

Another thought on the matter: The norm in our society has accepted the notion that red equals STOP or DANGER. So, it makes sense that the red color is used to designate the battery terminal that carries the higher voltage and the black color to represent the lower voltage terminal.

This system of representing wires in an electric circuit is always followed anywhere in the world. In the United States, they call the red wire the HOT wire because it is the wire that is alive. You will feel shocked when you touch this wire because it is live.

Do not let the two vehicles touch

Turn both vehicles off before locating the battery

What Occurs When A Negative Battery Terminal Is Connected To A Positive Battery Terminal

Electricity travels from negative to positive, so when you connect a negative terminal to a positive terminal, electricity flows through your vehicle and back into your battery. This is called a short circuit and it could cause serious damage to all of your vehicles electrical components.

Always follow the correct procedure when jumpstarting a car. If your battery terminals are marked with + and signs, then connecting them in that order will help ensure that you dont accidentally create a short circuit.

The safest way to determine which terminal is which is by using a voltmeter or multimeter. Connect one lead of your meter to each terminal on your battery and read the voltage listed on your meter. Use caution when testing your battery as you may get shocked if both terminals are connected at once. Your goal should be to test only one terminal at a time while keeping other terminals unconnected.

Testing either positive or negative first is up to you some people prefer doing it in that order because they feel like they have more control over what happens next. Once you have tested both sides of your battery make sure you put everything back together correctly and safely. When possible, avoid creating a short circuit when working with any kind of electronics. Short circuits can damage wires and break circuits inside sensitive devices.
