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:
CONNECT
TEST METER
LEADS TO:
Battery Charge Y1, Y2, or Y3
Coil to Ground
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
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.
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.

REGULATOR / RECTIFIER (DYNAMIX)

The dual regulator / rectifier assemblies are located
behind the front fascia grill 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 seat and disconnect the negative battery
terminal.
2. Remove the front fascia grill cover by pulling down on
the two tabs to release it.
3. Disconnect the two wiring harnesses going to the
regulator(s) being removed.
4. Remove the two fasteners
(s) to the mounting bracket.
5. Install new regulator(s) on the bracket. Torque
fasteners to specification.
