Understanding the Basics of Car Battery Wiring
Before we dive into the specifics of wiring accessories to a car battery, it’s essential to understand the basics of car battery wiring. A car battery is a 12-volt electrical system, which means that it operates on a negative ground system. This means that the negative terminal of the battery is connected to the chassis of the vehicle, while the positive terminal is connected to the starter motor and other accessories.
The car battery is also equipped with a range of terminals, including the positive terminal (+), the negative terminal (-), and the ground terminal (GND). The positive terminal is used to connect the starter motor and other accessories, while the negative terminal is used to connect the chassis of the vehicle. The ground terminal is used to connect the battery to the chassis and to provide a path for electrical current to flow.
Types of Car Battery Terminals
There are several types of car battery terminals, including:
- Top Post Terminals: These are the most common type of car battery terminal and are used in most vehicles.
- Side Post Terminals: These are used in some older vehicles and are typically found on batteries with a separate ground terminal.
- Stud Terminals: These are used in some high-performance vehicles and are designed to provide a more secure connection.
