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’
.
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.
