Auto Electrical Wiring Diagram Symbols
Common Auto Electrical Wiring Diagram Symbols
1. Battery: The symbol for a battery in a wiring diagram is usually represented by two parallel lines with a plus and minus sign at the ends. This symbol indicates the power source for the electrical system.
2. Ground: The ground symbol is typically shown as a horizontal line with three smaller lines branching off vertically. This symbol represents the connection to the vehicle’s chassis, which serves as a common ground point for the electrical system.
3. Fuse: The symbol for a fuse is usually depicted as a small, rectangular box with a diagonal line running through it. This symbol indicates a protective device that will break the circuit in case of an electrical overload.
4. Switch: The symbol for a switch is represented by a circle with a line through it. This symbol signifies a component that can open or close a circuit, controlling the flow of electricity to different parts of the vehicle.
5. Relay: The symbol for a relay is shown as a rectangle with a smaller rectangle inside and a diagonal line across the smaller rectangle. This symbol represents a device that acts as a switch, allowing a low-power signal to control a higher-power circuit.
Understanding these symbols and how they are used in auto electrical wiring diagrams can help you diagnose and repair electrical issues in your vehicle more efficiently. By familiarizing yourself with these symbols, you can confidently navigate through wiring diagrams and troubleshoot any problems that may arise.
In conclusion, auto electrical wiring diagram symbols play a crucial role in helping you understand the complex electrical systems in vehicles. By learning and recognizing these symbols, you can effectively troubleshoot and fix electrical issues in your vehicle, saving time and money in the process.
