pipe and check once again.
4. Tighten the high-pressure fuel hose to the specified torque.
Tightening torque: 5.0±1.0 N⋅m
INSPECTION
Check the following points; replace the part if a problem is
found.
INTAKE MANIFOLD CHECK
1. Check for damage or cracking of any part.
2. Check for obstruction of the negative pressure (vacuum)
outlet port, and for obstruction of the water passage or
gas passage.
3. Using a straight edge and thickness gauge, check for
distortion of the cylinder head installation surface.

CHARGING SYSTEM
GENERAL INFORMATION
The charging system uses the alternator output
to keep the battery charged at a constant level
under various electrical loads.
OPERATION
Rotation of the excited field coil generates AC voltage in
the stator.
This alternating current is rectified through diodes to DC
voltage having a waveform shown in the illustration at left.
The average output voltage fluctuates slightly with the
alternator load condition.
When the ignition switch is turned on, current flows
in the field coil and initial excitation of the field
coil occurs.
When the stator coil begins to generate power after
the engine is started, the field coil is excited by
the output current of the stator coil.
The alternator output voltage rises as the field
current increases and it falls as the field current
decreases. When the battery voltage (alternator
S terminal voltage) reaches a regulated voltageof approximately 14.4 V, the field current is cut
off. When the battery voltage drops below the
regulated voltage, the voltage regulator regulates
the output voltage to a constant level by controlling
the field current.
In addition, when the field current is constant, the
alternator output voltage rises as the engine speed
increases.

ALTERNATOR OUTPUT LINE VOLTAGE DROP TEST
Alternator
Terminal BVoltmeterAmmeter
Battery
+-
+-
This test determines whether the wiring from the
alternator “B” terminal to the battery (+) terminal
(including the fusible line) is in a good condition
or not.
(1) Always be sure to check the following before
the test.
DAlternator installation
DAlternator drive belt tension
(Refer to GROUP 11 - On-vehicle Service.)
DFusible link
DAbnormal noise from the alternator while
the engine is running
(2) Turn the ignition switch to the “LOCK” (OFF)
position.
(3) Disconnect the negative battery cable.
(4) Disconnect the alternator output wire from the
alternator “B” terminal and connect a DC test
ammeter with a range of 0 - 100 A in seriesbetween the “B” terminal and the disconnected
output wire. (Connect the (+) lead of the
ammeter to the “B” terminal, and then connect
the ( - ) lead of the ammeter to the disconnected
output wire.)
NOTE
An inductive-type ammeter which enables
measurements to be taken without
disconnecting the alternator output wire should
be recommended. Using this equipment will
lessen the possibility of a voltage drop caused
by a loose “B” terminal connection.
(5) Connect a digital-type voltmeter between the
alternator “B” terminal and the battery (+)
terminal. (Connect the (+) lead of the voltmeter
to the “B” terminal and the connect the ( - ) lead
of the voltmeter to the battery (+) cable.)
