Understanding the Wiring Diagram
The wiring diagram of the 2017 Polaris Sportsman 570 comprises several components that are interconnected to ensure the proper functioning of your ATV. These components include the battery, starter relay, starter motor, ignition switch, switch cluster, and various sensors.
The wiring diagram is a schematic representation of the electrical connections and circuits of the Polaris Sportsman 570. Each component is represented by a symbol, and the connections between them are shown by lines with arrows that indicate the direction of the electric current.
The wiring diagram is useful for troubleshooting electrical problems, identifying wire colors, and understanding how your ATV’s electrical system operates.
Battery
The battery is the primary source of electrical power for the Polaris Sportsman 570. It is connected to the starter relay through a positive cable and to the ground through a negative cable. The battery also powers the lights, accessories, and other electrical components of the ATV.
It’s important to keep the battery terminals clean and tight to ensure proper electrical contact. A weak battery can cause starting issues and other electrical problems.
Starter Relay and Starter Motor
The starter relay is an electromagnetic switch that connects the battery to the starter motor when the ignition switch is turned to the “on” position. The starter motor then cranks the engine to start it. If the starter relay fails, the ATV won’t start.
Make sure the starter relay connections are tight and clean. If the starter motor doesn’t crank the engine, check for a faulty starter relay or starter motor.
Ignition Switch and Switch Cluster
The ignition switch is a key-operated switch that turns on the ATV’s electrical system. It is connected to the switch cluster, which houses the headlight switch, kill switch, and other switches that control the ATV’s functions.
If the ignition switch fails, the ATV won’t start or run. Check the switch cluster for loose or damaged wires and connections. A faulty switch can cause a variety of electrical problems.
Sensors
The Polaris Sportsman 570 is equipped with several sensors that monitor various aspects of the ATV’s performance, such as the engine temperature, oil pressure, and throttle position. These sensors send signals to the ATV’s computer, which adjusts the fuel and ignition systems for optimum performance.
If a sensor fails or sends incorrect signals, the ATV’s performance can be affected. Check the wiring and connections of the sensors for damage, corrosion, or loose connections.
