If you’re a proud owner of a 1980 Yamaha XS850 and need a wiring diagram, you’ve come to the right place. In this article, we’ll provide you with a detailed overview of the bike’s electrical system, walk you through each component, and provide you with a comprehensive guide on how to read and interpret the wiring diagram.
Understanding the Electrical System
Before we jump into the wiring diagram, it’s essential to understand the XS850’s electrical system. The bike’s electrical system comprises various components, including the regulator/rectifier, the battery, the starter, the ignition switch, and the alternator. Each component plays a vital role in keeping the bike running, and any malfunction can lead to significant issues.
The regulator/rectifier is responsible for regulating the voltage output from the alternator and converting it from AC to DC. The battery stores energy and supplies it to the electrical system when the bike is not running. The starter, as the name suggests, helps start the engine, while the ignition switch controls the flow of electricity from the battery to the rest of the bike’s electrical system.
The alternator generates electricity as the engine runs and supplies power to the bike’s electrical system, such as the lights and the ignition system. Any issues with these components can lead to electrical issues, which can cripple your bike’s functionality.
