Charging System; Starting System - Daewoo CIELO EURO III Manual

Notice: Make sure the cables are not on or near pulleys,
fans, or other parts that will move when the engine
starts, damaging the parts.
4. Shift an automatic transaxle to PARK, or a manual
transaxle to NEUTRAL.
Caution: Do not use cables that have loose or miss-
ing insulation, or injury could result.
5. Clamp one end of the first jumper cable to the positive
terminal on the battery. Make sure it does not touch
any other metal parts. Clamp the other end of the
same cable to the positive terminal on the other bat-
tery. Never connect the other end to the negative ter-
minal of the discharged battery.
Caution: Do not attach the cable directly to the neg-
ative terminal of the discharged battery. Doing so
could cause sparks and possible battery explosion.
6. Clamp one end of the second cable to the negative
terminal of the booster battery. Make the final con-
nection to a solid engine ground, such as the engine
lift bracket, at least 450 millimeters (18 inches) from
the discharged battery.
7. Start the engine of the vehicle with the good battery.
Run the engine at a moderate speed for several min-
utes. Then start the engine of the vehicle which has
the discharged battery.
8. Remove the jumper cables by reversing the above
sequence exactly. Remove the negative cable from
the vehicle with the discharged battery first. While re-
moving each clamp, take care that it does not touch
any other metal while the other end remains at-
.

GENERATOR
The Delco-Remy CS charging system has several mod-
els available, including the CS-121D. The number de-
notes the outer diameter in millimeters of the stator
lamination.
CS generators are equipped with internal regulators. A
Delta stator, a rectifier bridge, and a rotor with slip rings
and brushes are electrically similar to earlier generators.
A conventional pulley and fan are used. There is no test
hole.
Unlike three-wire generators, the CS-121D may be used
with only two connections: battery positive and an ''L''
terminal to the charge indicator lamp. Use of the ''P,'' ''I,''
and ''S'' terminals is optional. The ''P'' terminal is con-
nected to the stator and may be connected externally to
a tachometer or other device.
As with other charging systems, the charge indicator
lamp lights when the ignition switch is turned to ON, and
goes out when the engine is running. If the charge indi-
cator is on with the engine running, a charging system

defect is indicated. This indicator light will glow at full
brilliance for several kinds of defects, as well as when
the system voltage is too high or too low.
The regulator voltage setting varies with temperature
and limits the system voltage by controlling the rotor
field current. The regulator switches rotor field current
on and off at a fixed frequency of about 400 hertz. By
varying the on-off time, correct average field current for
proper system voltage control is obtained. At high
speeds, the on-time may be 10 percent and the off-time
90 percent. At low speeds, with high electrical loads, on-
time may be 90 percent and the off-time 10 percent.

CHARGING SYSTEM

The Delco-Remy CS charging system has several mod-
els available, including the CS-121D. The number de-
notes the outer diameter in millimeters of the stator
laminations.
CS generators use a new type of regulator that incorpo-
rates a diode trio. A Delta stator, a rectifier bridge, and a
rotor with slip rings and brushes are electrically similar to
earlier generators. A conventional pulley and fan are
used. There is no test hole.
STARTER
Wound field starter motors have pole pieces, arranged
around the armature, which are energized by wound
field coils.
Enclosed shift lever cranking motors have the shift lever
mechanism and the solenoid plunger enclosed in the
drive housing, protecting them from exposure to dirt, icy
conditions, and splashes.
In the basic circuit, solenoid windings are energized
when the switch is closed. The resulting plunger and
shift lever movement causes the pinion to engage the
engine flywheel ring gear. The solenoid main contacts
close. Cranking then takes place.
When the engine starts, pinion overrun protects the ar-
mature from excessive speed until the switch is opened,
at which time the return spring causes the pinion to dis-
engage. To prevent excessive overrun, the switch
should be released immediately after the engine starts.

STARTING SYSTEM

The engine electrical system includes the battery, the
ignition, the starter, the generator, and all the related wir-
ing. Diagnostic tables will aid in troubleshooting system
faults. When a fault is traced to a particular component,
refer to that component section of the service manual.
The starting system circuit consists of the battery, the
starter motor, the ignition switch, and all the related elec-
trical wiring. All of these components are connected
