Generator Test (Undercharged Battery Check)S7RS0B1A04003
This condition, as evidenced by slow cranking or
indicator clear with dark or light yellow dot 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.1) Make sure that undercharged condition has not been caused by accessories left on for extended period of
time.
2) Check drive belt for proper tension.
3) If battery defect is suspected, refer to “Battery Description”.
4) Inspect wiring for defects. Check all connections for tightness and cleanliness, battery cable connections
at battery, starting motor, ignition ground cable and
no “C” terminal circuit at ground.
5) Connect switch (6), load (5), battery (4), voltmeter (3) and ammeter (2) to generator (1) as shown in
figure.
Voltmeter: Set between generator “B” terminal
and ground.
Ammeter: Set between generator “B” terminal
and battery (+) terminal.
NOTE
Use fully charged battery.

6) Measure current and voltage.
No-Load Check 1) Run engine from idling up to 2000 rpm and read meters.
NOTE
Turn off switches of all accessories (wiper,
heater etc.).

Specification for undercharged battery (No-load
check)
Current: 10 A
Voltage: 14.2 – 14.8 V (at 20 °C, 68 °F)
NOTE
Consideration should be taken that voltage
will differ somewhat with regulator case
temperature as shown in figure.

2) Using service wire, ground “C” terminal (1) of
generator.
3) Measure voltage between “B” terminal of generator and body ground.
Voltage: 12.5 – 13.1 V (at 20 °C, 68 °F)
• If voltage is higher than standard value
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.
Load Check 1) Run engine at 2000 rpm and turn on head light and blower motor.
2) Measure current. If measure current is less than 30 A, repair or
replace generator.
