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.
Each test should measure:

NOTE
Any measurement other than Infinity (open) will indicate

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.
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.

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
212° F or 100° C. If it turns off, verify the cooling fins are
clean, free from debris and that adequate airflow is
present.
REGULATOR REPLACEMENT
1. Remove the hood

2. Disconnect the two wiring harnesses
