ELECTRICAL TEST 2: Resistance Value of Stator Leg to Ground 1Measure the resistance value of each of the stator legs to ground: Y1 to Ground, Y2 to Ground, Y3 to GroundNOTE: Any measurement other than Infinity (open) will indicate failed or shorted stator legTEST 3: Measure AC Voltage Output of Each Stator Leg at Charging RPM 123Set the selector dial to measure AC VoltageStart the engine and let it idleWhile holding the ATV at specified RPM, separately measure the voltage across each "leg" of the stator by connecting the meter leads to the wires leading from the alternator (Y1 to Y2, Y1 to Y3, Y2 to Y3)4Refer to the table below for approximate Voltage AC readings according to RPMTest each leg at the specified RPM in the tableExample: The alternator voltage output reading should be approximately 18 Vac at 1300 RPM between each 'leg'NOTE: If one or more of the stator leg output AC voltage varies significantly from the specified value, the stator may need to be replacedAC VOLTAGE (VACREADING 18 Vac 42 Vac 64 Vac
