TEST 2: RESISTANCE VALUE OF EACH
STATOR LEG TO GROUND
1. Measure the resistance value of each of the stator
legs to ground: Y1 to Ground, Y2 to Ground, Y3 to
Ground.
2. Each test should measure:
Open Line (OL / ∞)
3. 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
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 / Inspection page
” 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.
NOTICE
If the regulator / rectifier case temperature exceeds
230° F or 110° C, the unit will turn itself off to cool down.
The unit will turn on again after it has cooled down to at
least 212° F or 100° C. If it turns off, verify the cooling
fins are clean, free from debris and that adequate
airflow is present.
