What Cable Goes On A Car Battery First: A Comprehensive Guide
When it comes to jump-starting a car battery or performing routine maintenance, knowing which cable to connect first is crucial. In this article, we’ll delve into the details of what cable goes on a car battery first, and provide a step-by-step guide to ensure a safe and successful experience.
Understanding the Basics
A car battery typically has two terminals: positive (+) and negative (-). The positive terminal is usually marked with a “+” sign or a red color, while the negative terminal is marked with a “-” sign or a black color. When jump-starting a car battery, it’s essential to connect the cables in the correct order to avoid any damage or electrical shock. (See Also: What Is Red On A Car Battery)
The Correct Connection Order
The correct connection order for jump-starting a car battery is as follows:
- Red (Positive) Cable: Connect the red positive cable to the positive terminal of the dead battery.
- Black (Negative) Cable: Connect the black negative cable to the negative terminal of the dead battery.
- Red (Positive) Cable: Connect the red positive cable to the positive terminal of the good battery.
- Black (Negative) Cable: Connect the black negative cable to a metal surface on the car’s engine or frame, away from the dead battery.
It’s essential to note that the red positive cable should always be connected to the positive terminal of the dead battery, and the black negative cable should always be connected to the negative terminal of the dead battery or a metal surface on the car’s engine or frame.
Why the Correct Connection Order Matters
Connecting the cables in the incorrect order can cause serious damage to the batteries, electrical system, or even the car’s engine. Here are some potential risks to consider:
- Short-Circuiting: Connecting the positive cable to the negative terminal or vice versa can cause a short-circuit, which can damage the batteries, electrical system, or even start a fire.
- Overcharging: Connecting the positive cable to the positive terminal of the dead battery can cause overcharging, which can damage the battery or electrical system.
- Electrical Shock: Connecting the cables in the incorrect order can also cause electrical shock or even electrocution.
Additional Tips and Precautions
When jump-starting a car battery, it’s essential to take additional precautions to ensure a safe and successful experience:
- Make sure the car is in park (automatic) or in gear (manual) and apply the parking brake.
- Ensure the good battery is fully charged and not damaged.
- Avoid touching any metal parts of the car or the battery while jump-starting.
- Keep the cables away from any moving parts or hot surfaces.
- Start the engine and let it run for a few minutes before disconnecting the cables.
Recap and Summary
In conclusion, connecting the cables in the correct order is crucial when jump-starting a car battery. The correct connection order is:
- Red (Positive) Cable: Dead battery positive terminal
- Black (Negative) Cable: Dead battery negative terminal
- Red (Positive) Cable: Good battery positive terminal
- Black (Negative) Cable: Metal surface on the car’s engine or frame
Remember to always follow the correct connection order to avoid any damage or electrical shock. Additionally, take additional precautions to ensure a safe and successful jump-starting experience. By following these guidelines, you’ll be able to jump-start your car battery with confidence and get back on the road in no time. (See Also: How Many Watts Car Battery)

Here are five FAQs related to “What Cable Goes On A Car Battery First”:
FAQs: What Cable Goes On A Car Battery First
What is the correct order for connecting cables to a car battery?
The correct order for connecting cables to a car battery is: negative (black) cable first, followed by the positive (red) cable. This order helps prevent any accidental short circuits that could cause damage to the battery or other electrical components.
Why is it important to connect the negative cable first?
Connecting the negative cable first helps prevent any accidental short circuits that could cause damage to the battery or other electrical components. When you connect the negative cable first, it helps to discharge any static electricity that may be present in the system, which can help prevent damage to sensitive electronics.

What happens if I connect the positive cable first?
If you connect the positive cable first, it can cause a surge of electricity to flow through the system, which can damage sensitive electronics and potentially cause a fire. This is because the positive cable is connected to the positive terminal of the battery, which is the source of the electrical current.
Can I use a multimeter to test the voltage of my car battery before connecting the cables?
Yes, you can use a multimeter to test the voltage of your car battery before connecting the cables. A multimeter can help you determine if the battery is fully charged, partially charged, or dead. This can help you determine the best course of action for jump-starting the car or replacing the battery.
What should I do if I accidentally connect the cables in the wrong order?
If you accidentally connect the cables in the wrong order, turn off the engine and disconnect the cables immediately. If you notice any signs of damage to the battery or other electrical components, have them checked and repaired by a professional mechanic as soon as possible.
