TEST 1: Resistance Value of Each Stator Leg 8. Example: The alternator current output reading
1. Measure the resistance value of each of the three should be approximately 21 VAC at 1300 RPM
stator legs: Y1 to Y2, Y1 to Y3, and Y2 to Y3. Each between each ‘leg’.
test should measure: 0.07 - 0.13 Ω
NOTICE
CONNECT OHMS If one or more of the stator leg output AC voltage varies
TEST METER READING significantly from the specified value, the stator may

Battery Charge READING
Coil Y1 to Y3 0.07 - 0.13 Ω
1300 21 VAC ± 25%

Coil Y2 to Y3 0.07 - 0.13 Ω 3000 47 VAC ± 25%
5000 79 VAC ± 25%
NOTICE
If there are any significant variations in ohm readings STATOR (ALTERNATOR) REPLACEMENT
between the three legs it is an indication that one of the
stator legs may be weak or failed. Refer to Chapter 3 – Stator Cover Removal /
Inspectionpage 3.43 procedure to service the stator.
TEST 2: Resistance Value of Each Stator Leg to NOTICE
Ground
The stator cover can be removed with the engine
2. Measure the resistance value of each of the stator installed in the chassis.
legs to ground: Y1 to Ground, Y2 to Ground, Y3 to
Ground. Be sure to thoroughly clean the area around the stator
cover prior to removal.
3. Each test should measure: Open Line (OL)
CONNECT OHMS
TEST METER READING
LEADS TO:
Battery Charge Y1, Y2, or Y3 Open Line
Coil to Ground (Infinity)
NOTICE
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.
