The diagram can be a bit daunting at first glance, but don’t worry. We’ll break it down into manageable sections to help you understand it better.

The Main Components

The main components of the 1979 XS650 wiring diagram include the battery, ignition switch, starter motor, alternator, regulator/rectifier, and ignition coil. These are the parts that work together to power your motorcycle.

The battery provides power to the whole system, while the ignition switch turns the motorcycle on and off. The starter motor cranks the engine to start it, while the alternator charges the battery while the engine is running. The regulator/rectifier regulates the voltage from the alternator, while the ignition coil provides the spark that ignites the fuel in the engine.

The Color-coded Wires

The wiring diagram is color-coded to help you identify which wire goes where. The colors of the wires on the diagram correspond to the colors of the wires on your motorcycle. This makes it easier to check for continuity between the wires and ensure that everything is connected correctly.

Black wires are ground wires, while red wires are power wires. Yellow wires are typically used for the lighting circuits, while blue wires are used for the ignition circuits. Green wires are often used for the charging circuits, while white wires are used for the main harness.

The Connections

The connections between the various components of the motorcycle are shown on the wiring diagram. The diagram shows which wires connect to which components and where they are located.

For example, the diagram shows that the positive battery terminal connects to the main fuse, which then connects to the ignition switch. The ignition switch then connects to the starter solenoid and the regulator/rectifier. The regulator/rectifier then connects to the alternator and the battery.
