Polaris Sportsman Xplorer 500 Starting System Wiring and Circuit (2000 model). The Polaris Sportsman Xporer 500 ignition exciter and trigger coils are located under the flywheel and are part of the stator assembly. The starting system consists of the starter motor, starter gears, solenoid and the handlebar-mounted starter button. An electrical diagram of the starting system is shown in below schematic. When the starter button is pressed, it engages the starter solenoid that completes the circuit allowing electricity to flow from the battery to the starter motor.
