ELECTRICAL
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.
Example: The alternator current output reading should be
approximately 18 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.
