OPERATION
When engine is stoppedWhen the ignition switch is switched to the “ON”
position, electricity flows from the
‘I” terminal of
the generator to the field coil, and at the same time
the charging warning light illuminates.
When engine is being started/has started
When the engine is started, charging voltage is ap-
plied to the ‘I” terminal of the generator, with the
result that the charging warning light is extinguished.
In addition, because battery voltage is applied to
the “S” terminal of the generator, this battery voltage
is monitored at the
IC voltage regulator, thus switch-ing ON and OFF the current to the field coil and
thereby controlling the output voltage of the genera-
tor.
Power is supplied to each load from the “B” terminal
of the generator.
NOTE
The generator relay functions as a back-up for the
flow of electricity to the field coil if there is a discon-
nection or damaged wiring of the charging warning
light.

TROUBLESHOOTING HINTS1. Charging warning light does not go on when
the ignition switch is turned to “ON”, before the
engine starts.l Check the bulb.
2.Charging warning light fails to go off once the
engine starts.l
Check the IC voltage regulator (located with-
in the generator).
3. Discharged or overcharged battery.l
Check the IC voltage regulator (located with-
in the generator).4. The charging warning light illuminates dimly.
l Check the diode (within the combination
meter) for a short-circuit.

ABNORMAL WAVE-FORMS EXAMPLES
NOTE
1.The size of the wave-form patterns differs largely depending on the adjustment of the variable knob
on the analyzer.
2.Identification of abnormal wave-forms is easier when there is a large output current (regulator is not
operating). (Wave-forms can be observed when the headlights are illuminated.)
3.Check the conditions of the charge light (illuminated/not illuminated) also, and carry out a total check.

dAbGENERATOR PULLEY REMOVAL
(1) Remove the bolts.
(2) Insert plain screwdriver between front bracket and
stator core and pry downward.
Caution
Do not insert screwdriver too deep, as there is
danger of damage to
stator coil.

\23ELOllINSPECTION
ROTOR
(1) Check field coil for continuity. Check to ensure that there
is continuity between slip rings.If resistance is extremely small, it means that there is
a short. If there is no continuity or if there is short circuit,
replace rotor assembly.
Resistance value : Approx. 3-5 Q
(2) Check field coil for grounding. Check to ensure that thereis no continuity between slip ring and core. If there is
continuity, replace rotor assembly.
STATOR
(1) Make continuity test on stator coil. Check to ensure that
there is continuity between coil leads.
If there is no continuity, replace
stator assembly.
(2) Check coil for grounding. Check to ensure that there is
no continuity between coil and core. If there is continuity,
replace stator assembly.
RECTIFIERS
(1) Positive Rectifier Test
Check for continuity between positive rectifier and stator
coil lead connection terminal with a circuit tester. If there
is continuity in both directions, diode is shorted. Replace
rectifier assembly.
