Understanding the Wiring Diagram
The wiring diagram for your 2003 Yamaha Grizzly 660 may seem complicated at first, but it’s actually fairly straightforward. Here are some of the key components you will find:
Battery
The battery is the heart of your ATV’s electrical system. It provides the power necessary to start the engine and run the lights and other accessories. The battery is connected to the starter, which is responsible for turning the engine over.
Starter
The starter is a small motor that turns the engine over when you turn the key. It’s important to make sure that your starter is in good condition and wired correctly, as a malfunctioning starter can prevent your ATV from starting.
Ignition switch
The ignition switch is what allows you to start and stop your ATV. When you turn the key, it sends a signal to the starter and the engine starts. When you turn the key back, the engine stops.
Charging system
The charging system is what keeps your battery charged while you are riding. It includes the stator, which generates electricity as the engine runs, and the rectifier-regulator, which converts the AC current generated by the stator into DC current that can be used to charge the battery.
Lights and accessories
Your ATV may have a number of lights and accessories, including headlights, taillights, turn signals, and a horn. These are all connected to the electrical system and require the proper wiring to function correctly.
