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)
S3RH0A1A04003
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.
