Grizzly 660 Wiring Diagram: Detailed Analysis
Battery
The battery is the source of power for the ATV’s electrical system. In the Grizzly 660, it is located under the seat. The wiring diagram shows that the positive terminal of the battery is connected to the starter motor and the fuse box. The negative terminal of the battery is connected to the frame of the ATV.
The battery’s voltage should be checked regularly to ensure that it is in good condition. If the voltage is low, it may be necessary to replace the battery.
Starter Motor
The starter motor is responsible for turning the engine over to start it. In the Grizzly 660, it is located on the left-hand side of the engine. The wiring diagram shows that the starter motor is connected to the battery and the ignition switch.
The starter motor can fail due to wear and tear, or due to electrical issues. If the starter motor fails, it will need to be replaced or repaired.
Ignition Switch
The ignition switch is responsible for turning the ATV’s electrical system on and off. In the Grizzly 660, it is located on the handlebars. The wiring diagram shows that the ignition switch is connected to the CDI and the starter motor.
If the ignition switch fails, the ATV will not start. It is recommended to check the ignition switch regularly, and if it shows any signs of wear, it should be replaced.
CDI
The CDI controls the ignition timing and spark. In the Grizzly 660, it is located under the seat. The wiring diagram shows that the CDI is connected to the ignition switch, the battery, and the spark plug.
If the CDI fails, the engine may not start, or it may run poorly. If the CDI shows any signs of wear or damage, it should be replaced.
Regulator/Rectifier
The regulator/rectifier regulates the voltage and converts AC power to DC power. In the Grizzly 660, it is located under the seat. The wiring diagram shows that the regulator/rectifier is connected to the alternator, the battery, and the fuse box.
If the regulator/rectifier fails, the battery may not charge properly, and the electrical system may malfunction. If the regulator/rectifier shows any signs of wear or damage, it should be replaced.
Alternator
The alternator generates electrical power for the ATV’s electrical system. In the Grizzly 660, it is located on the left-hand side of the engine. The wiring diagram shows that the alternator is connected to the regulator/rectifier.
If the alternator fails, the battery will not charge, and the ATV will not start. If the alternator shows any signs of wear or damage, it should be replaced.
Lights
The lights provide illumination for the ATV. In the Grizzly 660, the headlight is located on the front of the ATV, and the taillights are located on the rear. The wiring diagram shows that the lights are connected to the fuse box.
If the lights fail, it is recommended to check the bulbs and the connections. If they are in good condition, it may be necessary to replace the fuse or the wiring.
Fuse Box
The fuse box protects the electrical system from overloading and short-circuits. In the Grizzly 660, it is located under the seat. The wiring diagram shows that the fuse box is connected to the battery, the lights, and the regulator/rectifier.
If any electrical component fails, it is recommended to check the fuse first. If the fuse is blown, it should be replaced with a new one of the same rating. If the fuse blows repeatedly, it may indicate an underlying electrical issue that should be diagnosed and repaired.
Conclusion
The Yamaha Grizzly 660 wiring diagram is a comprehensive guide that provides details about the electrical connections, components, and their functions. Understanding the wiring diagram is essential for troubleshooting, repairing, or modifying your ATV’s electrical system. Regular maintenance and inspection of the electrical components, as well as the connections, can help ensure optimal performance and a longer lifespan of your Grizzly 660.
