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.
