Motorcycle Wiring Diagram Symbols Explained

The wiring diagram of a motorcycle can be complex and intimidating, but it doesn’t have to be. Knowing the symbols used in the diagram can help you understand what’s going on, and make it easier to diagnose and repair problems. Here, let’s take a look at some of the most commonly used symbols in motorcycle wiring diagrams and explain their meanings.

When looking at a wiring diagram, you may first notice the large, black rectangles. These are called “symbols” and represent the various components of the motorcycle. The symbol will usually have a number next to it, which indicates the specific part or piece of the diagram. For example, a 1 might indicate the starter motor, while a 21 might indicate the battery. Understanding these symbols is key to being able to read and understand the diagram.

The lines between the symbols are also important. These lines are called “connections”, and they dictate how the various components of the motorcycle come together and interact. They’re often represented by dashed lines, and their thickness indicates how much current is flowing between the two components. Thicker lines mean more current is flowing, while thinner lines mean less current is flowing. In addition, the direction of the line can tell you which way the current is flowing.

Finally, the arrows found in the diagram represent the flow of electricity. Arrows pointing away from a component indicate that electricity is leaving the component, while arrows pointing toward a component indicate that electricity is entering the component.

By understanding the symbols, connections, and arrows used in motorcycle wiring diagrams, you can easily diagnose and repair problems with your bike. Knowing what each symbol means can make it much easier to understand what’s going on and get your bike running again in no time.
