NOTE
If there are any significant variations in ohm readings
between the three legs it is an indication that one of the
stator legs may be weak or failed.
TEST 2: RESISTANCE VALUE OF EACH STATOR
LEG TO GROUND
Measure the resistance value of each of the stator legs to
ground: Y1 to Ground, Y2 to Ground, Y3 to Ground.

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).

REGULATOR / RECTIFIER (NON-DYNAMIX)

The regulator / rectifier is located under the hood in front
of the radiator.
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
OHMS
212° F or 100° C. If it turns off, verify the cooling fins are

clean, free from debris and that adequate airflow is
present.
