6H-4 CHARGING SYSTEM
GENERATOR
The generator is a small and high performance type with an IC regulator incorporated.
The internal components are connected electrically as shown below figure.
The generator features are as follows:
Solid state regulator is mounted inside the generator.
All regulator components are enclosed into a solid mold.
This unit along with the brush holder assembly is attached to the rear housing.
The IC regulator uses integrated circuits and controls the voltage produced by the generator, and the volt-
age setting cannot be adjusted.
The generator rotor bearings contain enough grease to eliminate the need for periodic lubrication. Two
brushes carry current through the two slip rings to the field coil mounted on the rotor, and under normal con-
ditions will provide long period of attention-free service.
The stator windings are assembled on the inside of a laminated core that forms part of the generator frame.
A condenser mounted in the rear housing suppresses radio noise.

6H-6 CHARGING SYSTEM
GENERATOR
Trouble in charging system will show up as one or more of the fol-
lowing conditions:
1) Faulty indicator lamp operation.
2) An undercharged battery as evidenced by slow cranking or
indicator dark.
3) An overcharged battery as evidenced by excessive spewing
of electrolyte from vents.
Noise from generator may be caused by loose drive pulley, loose
mounting bolts, worn or dirty bearings, defective diode, or defec-
tive stator.
CHARGING INDICATOR LAMP OPERATION
CAUTION:
Do not mistake polarities of IG terminal and L terminal.
Do not create short circuit between IG and L terminals.
Always connect these terminals through a lamp.
Do not connect any load between L and E.
When connecting charger or booster battery to vehicle
battery, refer to this section describing battery charg-
ing.

Condition Possible Cause Correction
Charge light does not
light with ignition ON
and engine offFuse blown Check fuse.
Light burned out Replace light.
Wiring connection loose Tighten loose connection.
IC regulator or field coil faulty Check generator.
Poor contact between brush and slip ring Repair or replace.
Charge light does not go
out with engine running
(battery requires fre-
quent recharging)Drive belt loose or worn Adjust or replace drive belt.
IC regulator or generator faulty Check charging system.
Wiring faulty Repair wiring.
