To test a voltage regulator on a snowmobile, start by checking the battery voltage with a multimeter; it should read around 12.6 volts when fully charged. Next, start the snowmobile and measure the voltage across the battery again; it should increase to about 13.5 to 14.5 volts if the regulator is functioning properly. If the voltage remains low or exceeds 15 volts, the regulator may be faulty. Additionally, inspect the regulator for any physical damage or loose connections.

To test a 2006 Bombardier DS650 Baja X voltage regulator, first, ensure the ATV is turned off and disconnect the battery. Using a multimeter, check the resistance between the regulator's terminals; a reading of infinite ohms indicates a faulty regulator. Next, start the engine and measure the output voltage at the regulator; it should read between 13.5 to 14.5 volts at idle. If the voltage is outside this range or fluctuates significantly, the voltage regulator may need replacement.
