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.
8. Example: The alternator current output reading
should be approximately
18 VAC at 1300 RPM
between each ‘leg’.
NOTICE
If one or more of the stator leg output AC voltage varies
significantly from the specified value, the stator may
need to be replaced.

IMPORTANT
Before starting, engine temperature must be cool
enough to prevent fan activation. Fan activation will
cause a false reading.
1. With the engine off, disconnect the DC connectors
q
on both regulators.
2. Connect a multi-meter to the battery and observe
battery voltage.
3. Start the engine and allow voltage to stabilize.
IMPORTANT
Ensure the headlights are off, and the cooling fan does
not activate.
4. Connect the DC connectors one at a time while
observing battery voltage. A properly operating
regulator will cause battery voltage to rise by a few
tenths of a volt or more.
a. If the voltage does not rise by a few tenths of a
volt, replace the suspect regulator.
