Alternator Output Test
Three tests can be performed using a multimeter to
determine the condition of the stator (alternator).
TEST 1: Resistance Value of Each Stator Leg
1. Measure the resistance value of each of the three
stator legs: Y1 to Y2, Y1 to Y3, and Y2 to Y3. Each
should measure 0.22 Ω ± 15%.

NOTE: If there are any significant variations in
ohm's readings between the three legs; it is an
indication that one of the three stator legs maybe
weak or failed.
TEST 2: Resistance Value of Stator Leg to Ground
2. Measure the resistance value of each of the stator
legs to ground: Y1 to Ground, Y2 to Ground, Y3 to
Ground.
NOTE: Any measurement other than Infinity
(open) will indicate a failed or shorted stator leg.
TEST 3: Measure AC Voltage Output of Each
Stator Leg at Charging RPM
3. Set the selector dial to measure AC Voltage.
4. Start the engine and let it idle.
5. While holding the ATV at a 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).
6. Refer to the table below for approximate Voltage AC
readings according to RPM. Test each leg at the
specified RPM in the table. Example: 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 replaced.
