Are you having trouble figuring out the wiring diagram for your 1979 Yamaha XS750? Look no further, as this article will guide you through the process step-by-step. With the help of this article, you’ll be able to easily understand the wiring diagram and have your motorcycle up and running in no time.
Understanding the Wiring Diagram
The wiring diagram may seem intimidating at first, but it’s actually a simple diagram that shows how all the electrical components in your motorcycle are connected. The diagram consists of symbols that represent each component and lines that represent the electrical connections between them.
Before you begin, it’s essential to have a basic understanding of the components and their symbols. Here’s a breakdown of some common symbols that you’ll encounter in the diagram:
Battery
The battery symbol represents the power source of your motorcycle. It’s usually located on the top left corner of the diagram and is represented by a rectangle with a plus and minus sign.
Ignition Switch
The ignition switch symbol is represented by a rectangle with the letter “I” inside. It’s usually located on the top right corner of the diagram and is responsible for turning on and off the engine.
Spark Plug
The spark plug symbol is represented by a triangle with a line attached to it. It’s usually located in the middle of the diagram and is responsible for igniting the fuel in the engine.
Coil
The coil symbol is represented by a rectangle with two lines attached to it. It’s usually located near the spark plug and is responsible for converting the battery’s voltage into high voltage for the spark plug to ignite the fuel.
Understanding these symbols will make it easier to read and understand the wiring diagram.
Step-by-Step Guide
Now that you have a basic understanding of the symbols, it’s time to dive into the wiring diagram. Here’s a step-by-step guide to help you understand the diagram:
Step 1: Battery Connection
The first step is to connect the battery to the motorcycle. Look for the battery symbol on the top left corner of the diagram and trace the line that connects it to the rest of the electrical components. Check if there are any fuses or switches in between the battery and the components.
Step 2: Ignition Switch Connection
The next step is to connect the ignition switch. Look for the ignition switch symbol on the top right corner of the diagram and trace the line that connects it to the engine and other electrical components. Make sure that the ignition switch is connected properly and can turn on and off the engine.
Step 3: Spark Plug Connection
The third step is to connect the spark plug. Look for the spark plug symbol in the middle of the diagram and trace the line that connects it to the coil and battery. Check that the coil is connected properly and is producing high voltage for the spark plug.
Step 4: Headlight Connection
The last step is to connect the headlight and other electrical components. Look for the symbols that represent the electrical components and trace the lines that connect them to the battery and other components. Check that all the connections are secure and that the electrical components are functioning properly.
