Charging System Symptom Diagnosis

Condition
Generator does not
charge
Generator does charge,
but charging rate is below
the specification
Generator overcharges
Unstable charging
"Sulfation", acidic white
powdery substance or
spots on surfaces of cell
plates
Battery runs down quickly Trouble in charging system.
Battery "sulfation"

Diagnostic Information and Procedures

Possible cause
Open- or short-circuited lead wires, or
loose lead connections.
Short-circuited, grounded or open
generator coils.
Short-circuited or punctured IC regulator
or rectifier.
Lead wires tend to get short- or open-
circuited or loosely connected at
terminals.
Grounded or open-circuited stator coils
or generator.
Defective IC regulator or rectifier
Defective cell plates in the battery.
Internal short-circuit in the battery.
Damaged or defective IC regulator or
rectifier.
Poorly grounded IC regulator.
Poor contact of generator lead wire
coupler.
Lead wire insulation frayed due to
vibration, resulting in intermittent short-
circuitting.
Internally short-circuited generator.
Defective IC regulator or rectifier.
Cracked battery case.
Battery has been left in a run-down
condition for a long time.
Cell plates have lost much of their active
materials a result of overcharging.
Internal short-circuit in the battery.
Too low battery voltage.
Too old battery.
Incorrect charging rate. (When not in
use battery should be checked at least
once a month to avoid sulfation.)
The battery was left unused in a cold
climate for too long.
