Stator (Alternator) Replacement - Polaris RZR XP 1000 2014 Service Manual

ELECTRICAL
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
test should measure: 0.07 - 0.13 Ω

If there are any significant variations in ohm readings
between the three legs it is an indication that one of the
stator legs may be weak or failed.
TEST 2: Resistance Value of Each 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.
3. Each test should measure: Open Line (OL)

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
4. Set the selector dial to measure AC Voltage.
5. Start the engine and let it idle.
6. While holding the engine 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).
7. Refer to the following table for approximate AC
Voltage readings according to RPM. Test each leg at
the specified RPM in the table.

8. Example: The alternator current output reading
should be approximately 21 VAC at 1300 RPM
between each 'leg'.
If one or more of the stator leg output AC voltage varies
significantly from the specified value, the stator may
need to be replaced.

STATOR (ALTERNATOR) REPLACEMENT

Refer to Chapter 3 – Stator Cover Removal / Inspection,
page 3.47 procedure to service the stator.
The stator cover can be removed with the engine
installed in the chassis.
Be sure to thoroughly clean the area around the stator
cover prior to removal.
