2000 SUZUKI SWIFT engine

6H-8 CHARGING SYSTEM
3) Ground F terminal and start engine, then measure voltage at
B terminal as shown in left 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
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.
OVERCHARGED BATTERY
1) To determine battery condition, refer to Battery section.
2) If obvious overcharge condition exists as evidenced by
excessive spewing of electrolyte, measure generator B ter-
minal voltage at engine 2000 rpm.
3) If measured voltage is higher than upper limit value, disas-
semble generator.
4) Check ground of brushes. If brushes are not grounded,
replace IC regulator. Then check field coil for grounds and
shorts.

ON-VEHICLE SERVICE
BATTERY
JUMP STARTING IN CASE OF EMERGENCY
WITH AUXILIARY (BOOSTER) BATTERY
Both booster and discharged battery should be treated carefully when using jumper cables. Follow procedure
outlined below, being careful not to cause sparks.
1) Set parking brake and place automatic transmission in PARK (NEUTRAL on manual transmission). 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 vehi-
cle with discharged battery.
6) Disconnect jumper cables in the exact reverse order.
WITH CHARGING EQUIPMENT
CAUTION:
If vehicle is manual transmission 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.
WARNING:
Departure from these conditions or procedure described below 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.
WARNING:
Do not connect negative cable directly to negative terminal of dead battery.
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.

6H-10 CHARGING SYSTEM
DISMOUNTING
1) Disconnect negative cable (1).
2) Disconnect positive cable (2).
3) Remove retainer (3).
4) Remove battery (4).
HANDLING
When handling battery, following safety precautions should be
followed:
Hydrogen gas is produced by battery. A flame or spark near
battery may cause the gas to ignite.
Battery fluid is highly acidic. Avoid spilling on clothing or
other fabric. Any spilled electrolyte should be flushed with
large quantity of water and cleaned immediately.
REMOUNTING
1) Reverse removal procedure.
2) Torque battery cables to specification.
Tightening torque
Body ground bolt (a): 8.0 N·m (0.8 kg-m, 6.0 lb-ft)
GENERATOR
GENERATOR BELT
Refer to “WATER PUMP BELT” in Section 6B “ENGINE COOL-
ING”.
5. Body ground bolt
6. Nut
NOTE:
Check to be sure that ground cable has enough clear-
ance to hood panel by terminal.

6K-4 EXHAUST SYSTEM
EXHAUST MANIFOLD
REMOVAL AND INSTALLATION
Refer to Section 6A1 for removal and installation procedures of exhaust manifold.
INSPECTION
Check gasket and seal for deterioration or damage.
Replace them as necessary.
EXHAUST PIPE
REMOVAL AND INSTALLATION
For replacement of exhaust pipe, be sure to hoist vehicle and observe WARNING under “MAINTENANCE” and
the following.
Tighten bolts and nuts to specified torque when reassembling. Refer to “GENERAL DESCRIPTION” for
location of bolts and nuts.
After installation, start engine and check each joint of exhaust system for leakage. CAUTION:
Exhaust pipe have three way catalytic converter in it, it should not be exposed to any impulse.
Be careful not to drop it or hit it against something.
