Diagnostic Information and Procedures
Battery InspectionS6RW0D1A04001
Common Causes of Failure
A battery is not designed to last indefinitely; however,
with proper care, it will provide many years of service. If
the battery performs satisfactorily during test buy fails to
operate properly for no apparent reason, the following
are some factors that may point to the cause of trouble:
• Accessories left on overnight or for an extended
period without the generator operating.
• Slow average driving speed for short periods.
• Electrical load exceeding generator output particularly
with addition of aftermarket equipment.
• Defects in charging system such as high resistance,
slipping drive belt, loose generator output terminal,
faulty generator or voltage regulator. Refer to
“Generator Symptom Diagnosis”.
• Battery abuse, including failure to keep battery cable
terminals clean and tight or loose battery hold down.
• Mechanical problems in electrical system such as
shorted or pinched wires.
Visual Inspection
Check for obvious damage, such as cracked or broken
case or cover, that could permit loss of electrolyte. If
obvious damage is noted, replace battery. Determine
cause of damage and correct as needed.
Generator Symptom DiagnosisS6RW0D1A04002
CAUTION!
• Do not mistake polarities of “IG” terminal
and “L” terminal.
• Do not create short circuit between “IG”
and “L” terminals. Always connect these
terminals through a lamp.
• Do not connect any load between “L” and
“E” terminals.
• When connecting charger or booster
battery to vehicle battery, refer to “Jump
Starting in Case of Emergency”.

Trouble in charging system will show up as one or more
of the following conditions:
1) Faulty indicator lamp operation.
2) An undercharged battery as evidenced by slow
cranking or indicator dark.
3) An overcharged battery as evidenced by excessive
spewing of electrolyte from vents.
Noise from generator may be caused by loose drive
pulley, loose mounting bolts, worn or dirty bearings,
defective diode, or defective stator.

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.

1) Set parking brake and place automatic transaxle in
PARK (NEUTRAL on manual transaxle). Turn off
ignition, turn off lights and all other electrical loads.
2) Check electrolyte level. If it is below low level line,
add distilled water.
3) Attach end of one jumper cable to positive terminal
of booster battery and the other end of the same
cable to positive terminal of discharged battery. (Use
12-volt battery only to jump start engine).
4) Attach one end of the remaining negative cable to
negative terminal of booster battery, and the other
end to a solid engine ground (such as exhaust
manifold) at least 45 cm (18 in.) away from battery of
vehicle being started.
5) Start engine of vehicle with booster battery and turn
off electrical accessories. Then start engine of the
vehicle with discharged battery.
6) Disconnect jumper cables in the exact reverse order.
With Charging Equipment
CAUTION!
When jump starting engine with charging
equipment, be sure equipment used is 12-
volt and negative ground. Do not use 24-volt
charging equipment. Using such equipment
can cause serious damage to electrical
system or electronic parts.
