If you are a proud owner of a 1981 Yamaha XS650 motorcycle, you might want to keep a copy of the wiring diagram handy. The wiring diagram is a visual representation of the electrical connections and wiring of the motorcycle, and it can be extremely useful when troubleshooting electrical issues or making modifications to the bike’s electrical system.
Overview of the Electrical System
The XS650’s electrical system consists of a battery, alternator, regulator/rectifier, ignition system, and various switches and relays. The battery is responsible for powering the ignition system and other electrical components when the engine is not running, while the alternator charges the battery and provides power to the motorcycle when the engine is running.
The regulator/rectifier is responsible for regulating the voltage output of the alternator and converting it to a direct current (DC) that can be used by the motorcycle’s electrical system. The ignition system consists of the spark plugs, ignition coils, and various sensors and switches that control the timing and delivery of the spark to the engine.
