1J-4 Charging System:
Charging Indicator Lamp Operation
Generator Test (Undercharged Battery Check)
S4RS0A1A04003
This condition, as evidenced by slow cranking or low
specific gravity can be caused by one or more of the
following conditions even though indicator lamp may be
operating normal. The following procedure also applies
to cars with voltmeter and ammeter.
• Make sure that undercharged condition has not been
caused by accessories left on for extended period of
time.
• Check drive belt for proper tension.
• If battery defect is suspected, refer to “Battery
Description: ”.
• Inspect wiring for defects. Check all connections for
tightness and cleanliness, battery cable connections
at battery, starting motor and ignition ground cable.
No-Load Check
1) Connect voltmeter and ammeter as shown in the
figure.
NOTE:
Use fully charged battery.
2) Run engine from idling up to 2,000 rpm with all
accessories turned off and read meters.
If voltage is higher than standard value, check
ground of brushes.
If brushes are not grounded, replace IC regulator.
If voltage is lower than standard value, proceed to
the following check.
