How To Tell Which Is Positive And Negative On A Car Battery?

If your car battery is starting to show signs of wear, you may be wondering how to tell which is the positive and negative terminal. While there are a few ways to tell, the most reliable method is to check the markings on the battery itself. The positive terminal will typically be marked with a “+” sign, while the negative terminal will be marked with a “-” sign. If you’re still unsure, you can consult your car’s owner’s manual for more information.

Right Way to Use Jumper Cables

If you find yourself in a situation where you need to use jumper cables to start your car, it is important to know which is the positive and which is the negative terminal on the battery. The positive terminal is usually marked with a “+” sign, and the negative terminal is usually marked with a “-” sign. If you are not sure which is which, you can always consult your car’s owner’s manual.

Once you have located the positive and negative terminals on the battery, it is important to connect the cables in the correct order. First, connect the positive cable to the positive terminal on the battery. Then, connect the negative cable to the negative terminal on the battery. Finally, connect the other end of the positive cable to the positive terminal on the other battery.

Once the cables are connected, you can start your car. Be sure to let the car run for a few minutes before disconnecting the cables, as this will help to recharge the battery.

What Happens if Battery Cables are Hooked Up Backwards?

If you hook up your battery cables backwards, a few things can happen. The most common is that your car won’t start. This is because the electrical current flows from the positive terminal to the negative terminal. If you reverse the cables, the current can’t flow and your car won’t start.

Another thing that can happen is that you can damage your car’s electrical system. This is because the current will flow through the system backwards and can fry components like your alternator or fuse box.

So, if you’re ever unsure which battery terminal is which, always check your car’s owner’s manual before hooking up the cables. And, if you’re still unsure, you can always ask a qualified mechanic to help you out.
