CHARGING SYSTEM Troubleshooting
Name Symbol
Alternator relay A
- H A L
When the ignition switch is switched to the
position, electricity flows from the “L” terminal, of the
alternator to the field coil, and at the same time the
charging warning light illuminates.
When the engine is started, charging voltage is
applied to the “L” terminal of the alternator, with the
result that the charging warning light is extinguished.
addition, because battery voltage is applied to the
“S” terminal of the alternator, this battery voltage is
monitored at the voltage regulator, thus switching
ON and OFF the current to the field coil and thereby
controlling the amount of generation by the
alternator.
Power is supplied to each load from the
terminal
of the alternator.
NOTE
The alternator relay functions as a back-up for the
flow of electricity to the field coil if there is a
disconnection or damaged wiring of the charging
warning light.
1. Charging indicator light does not go on when the
ignition switch is turned to “ON”, before the
engine starts.
l Check the bulb
2. Charging indicator light fails to go off once the
engine starts.
Check the voltage regulator (located within
the alternator).
3. Discharged or overcharged battery.
Check the voltage regulator (located within
the alternator).
4. The charging warning light illuminates dimly.
Check the diode (within the combination
meter) for a short-circuit.
