The charging system on the 1980 Yamaha XS650 was a three-phase alternator system, consisting of a stator, rotor, and rectifier/regulator. The wiring diagram shows how the alternator is connected to the battery, charging system, and other components.

Table 2: Charging System Components

Component Color Connector
Stator White & White/Red 4 & 5
Rotor N/A N/A
Rectifier/Regulator Red, Green, & Black 6
Battery Red

As you can see, the stator is connected to the rectifier/regulator, which in turn is connected to the battery. The rotor is not shown in the wiring diagram, as it is a rotating component that does not have any electrical connections.

Lighting System

The lighting system on the 1980 Yamaha XS650 includes the headlight, tail light, turn signals, and brake light. The wiring diagram shows how these components are connected to the bike’s electrical system.

Table 3: Lighting System Components

Component Color Connector
Headlight Blue/White & Blue/Yellow 7 & 8
Tail light Brown & Brown/White 9 & 10
Turn Signals Orange & Light Blue 11 & 12
Brake Light Green & Green/White 13 & 14

The wiring diagram shows how the headlight, tail light, and turn signals are connected to the bike’s battery, while the brake light is wired in series with the brake switch and the bike’s electrical system.
