TEST 3: MEASURE AC VOLTAGE OUTPUT OF
EACH STATOR LEG AT CHARGING RPM
1. Set the selector dial to measure AC Voltage.
2. Start the engine and let it idle.
3. 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).
4. Refer to the following table for approximate AC
Voltage readings according to RPM. Test each leg at
the specified RPM in the table.
5. Example: The alternator current output reading
should be approximately 21 VAC ± 25% at 1300 RPM
between each ‘leg’.
6. 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 “Stator Cover Removal / Inspectionpage
3.45” for stator service.
NOTICE
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.
REGULATOR / RECTIFIER OPERATION
The regulator / rectifier is mounted behind the front
bumper.
