To test the charging system on a Polaris Sportsman 400, start by checking the battery voltage with a multimeter; it should read around 12.6 volts when fully charged. Next, start the engine and measure the voltage at the battery again; it should increase to about 13.5 to 14.5 volts if the charging system is working correctly. Additionally, inspect the connections and wiring for any signs of damage or corrosion. If the voltage does not rise, the voltage regulator or stator may be faulty and should be tested or replaced.
