Starting Motor InspectionS6RW0D1906003
Plunger
Inspect plunger for wear. Replace if necessary.
Magnetic Switch
Push in plunger and release it. The plunger should
return quickly to its original position. Replace if
necessary.
Pull-in coil open circuit test
Check for continuity across magnetic switch “S” terminal
(1) and “M” terminal (2). If no continuity, coil is open and
should be replaced.Hold-in coil open circuit test
Check for continuity across magnetic switch “S” terminal
(1) and coil case. If no continuity, coil is open and should
be replaced.
Rear Bracket Bush
Inspect bush for wear or damage. Replace if necessary.
Brush
• Check brushes for wear.
Measure length of brushes and if below the limit,
replace the brush.
Brush length
Standard: 12.3 mm (0.48 in.)
Limit: 7.0 mm (0.28 in.)
• Install brushes to each brush holder and check for

Charging Indicator Lamp Operation
Generator Test (Undercharged Battery Check)S6RW0D1A04003
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 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.
Specification for undercharged battery (No-load
check)
Current: 10 A
Voltage: 14.2 – 14.8 V at Hi (H) (at 25 °C, 77 °F)
Voltage: 12.5 – 13.1 V at Lo (L) (at 25 °C, 77 °F)
NOTE
Consideration should be taken that voltage
will differ somewhat with regulator case
temperature as shown in figure.

3) Ground “F” terminal and start engine, then measure
voltage at “B” terminal as shown in figure.
• Voltage is higher than standard value. It is
considered that generator itself is good but IC
regulator has been damaged, replace IC
regulator.
• Voltage is lower than standard value. It is
considered that generator itself has problem,
check the generator.
Load Check
1) Run engine at 2,000 rpm and turn on head light and
heater motor.
2) Measure current and if it is less than 20 A, repair or
replace generator.Generator Test (Overcharged Battery Check)S6RW0D1A04004
1) To determine battery condition, refer to “Battery
Description”.
2) If obvious overcharged condition exists as evidenced
by excessive spewing of electrolyte, measure
generator “B” terminal voltage at engine 2000 rpm.
3) If measured voltage is higher than upper limit value,
disassemble generator.
4) Check ground of brushes. If brushes are not
grounded, replace IC regulator. Then check field coil
for grounds and shorts.
Repair Instructions
Jump Starting in Case of EmergencyS6RW0D1A06001
With Auxiliary (Booster) Battery
CAUTION!
If vehicle is manual transaxle model and has
a catalytic converter, do not push or tow it to
start. Damage to its emission system and/or
to other parts may result.

Both booster and discharged battery should be treated
carefully when using jumper cables. Follow the
procedure outlined as follows, being careful not to cause
sparks.
WARNING!
• Departure from these conditions or
procedure described as follows could
result in:
– Serious personal injury (particularly to
eyes) or property damage from such
causes as battery explosion, battery
acid, or electrical burns.
– Damage to electronic components of
either vehicle.
• Remove rings, watches, and other jewelry.
Wear approved eye protection.
• Be careful so that metal tools or jumper
cables do not contact positive battery
terminal (or metal in contact with it) and
any other metal on vehicle, because a
short circuit could occur.
• Do not connect negative cable directly to
negative terminal of dead battery.
