If you own a 1990 Kawasaki Bayou 220 ATV, then you know how important it is to have an accurate wiring diagram. The wiring diagram is a vital tool that helps you understand the electrical system of your ATV. In this article, we will examine the wiring diagram of the 1990 Kawasaki Bayou 220 ATV.
Introduction
The 1990 Kawasaki Bayou 220 ATV is equipped with a four-stroke, air-cooled engine. It has a maximum power output of 16 horsepower and a top speed of 45 miles per hour. The ATV also features a solid rear axle, a five-speed manual transmission, and a dual-range transfer case.
The electrical system of the ATV consists of a battery, a starter motor, an alternator, a voltage regulator, and various switches and sensors. All of these components are connected by a network of wires and cables, which are routed throughout the ATV.
Wiring Diagram
The wiring diagram of the 1990 Kawasaki Bayou 220 ATV is shown in the table below. This diagram illustrates the connections between the various electrical components of the ATV.
| Component | Color | Wire Gauge | Connection |
|---|---|---|---|
| Battery | N/A | N/A | Positive to Starter Motor, Negative to Ground |
| Starter Motor | Red | 10 Gauge | Positive from Battery |
| Alternator | Yellow | 14 Gauge | Positive from Battery |
| Voltage Regulator | Black | 14 Gauge | Ground |
| Ignition Switch | Red/Black | 14 Gauge | Positive from Battery |
Battery
The battery is the primary source of power for the ATV. It supplies power to the starter motor, the lights, and other electrical components. The positive battery terminal is connected to the starter motor, while the negative terminal is connected to the ground.
The battery should be fully charged before starting the ATV. A weak or dead battery can cause starting problems and can also damage the electrical system of the ATV.
Starter Motor
The starter motor is responsible for cranking the engine and starting the ATV. It is connected to the positive terminal of the battery via a red wire. When the ignition switch is turned on, power is supplied to the starter motor, which then engages the engine.
A faulty starter motor can cause starting problems, such as slow cranking or no cranking at all. If you suspect that the starter motor is faulty, it should be tested and replaced if necessary.
Alternator
The alternator is responsible for charging the battery and supplying power to the electrical system of the ATV. It is connected to the positive terminal of the battery via a yellow wire. When the engine is running, the alternator generates electrical power, which is then used to charge the battery and power the ATV’s electrical components.
If the alternator is faulty, the battery may not be charged properly, and the electrical system may not function correctly. A faulty alternator should be tested and replaced if necessary.
Voltage Regulator
The voltage regulator is responsible for regulating the electrical output of the alternator. It is connected to the ground via a black wire. The voltage regulator ensures that the voltage output of the alternator remains within a safe range, which helps to prevent damage to the electrical system of the ATV.
Ignition Switch
The ignition switch is responsible for controlling the power supply to the electrical system of the ATV. It is connected to the positive terminal of the battery via a red/black wire. When the ignition switch is turned on, power is supplied to the ATV’s electrical components, including the starter motor, lights, and other accessories.
FAQ
1. What should I do if my ATV won’t start?
If your ATV won’t start, check the battery to make sure it is fully charged. Also, check the starter motor to make sure it is functioning correctly. If necessary, test the alternator and voltage regulator to ensure they are working properly. If you are still having issues, you may need to take your ATV to a professional mechanic for further diagnosis and repair.
2. How often should I check my ATV’s electrical system?
