battery, electricity is forced into the battery
, and the battery is returned to its fully
charged state.
Alternators are used on the modern autom obiles for they are lighter, more
efficient, can rotate at higher speeds and have fewer brush problems. In an
alternator, the field rotates while al l the current produced passes only through
the stators windings. The brushes bear agains t continuous slip rings rather than
a commutator. This causes the current produced to periodically reverse the
direction of its flow. Diodes (electrica l one-way switches) block the flow of
current from traveling in t he wrong direction. A series of diodes is wired together
to permit the alternating flow of the st ator to be converted to a pulsating, but
unidirectional flow at the alternator out put. The alternator's field is wired in
series with the voltage regulator.
Please refer to Engine Performance & Tune-up for ignition system testing
procedures.

ALTERNATOR
DESCRIPTION
An alternator differs from a DC shunt generator in that the armature is
stationary, and is called the stator, while the field rotates and is called the rotor.
The higher current values in the alternator's stator are conducted to the external
circuit through fixed leads and connecti ons, rather than through a rotating
commutator and brushes as in a DC generator. This eliminates a major point of
maintenance.
The rotor assembly is supported in the drive end frame by a ball bearing and at
the other end by a roller bearing. These bearings are lubricated during
assembly and require no main tenance. There are six diodes in the end frame
assembly. These diodes are electrical check valves that also change the

INTAKE MANIFOLD
REMOVAL & INSTALLATION
When servicing all vehicles, be absolutel y sure to mark vacuum hoses and
wiring so that these items may be properly reconnected during installation. Also,
when disconnecting fitting lines (fuel lines, power brake vacuum lines,
transmission and engine cooler lines, etc.), always use two flare nut (or line)
wrenches. Hold the wrench on the large fitti ng with pressure on the wrench as if
you were tightening the fitting (clockw ise), THEN loosen and disconnect the
smaller fitting from the larger fitting. If this is not done, damage to the line will
result. Always relieve fuel system pressure before disconnecting lines.
CAUTION - When draining the coolant, keep in mind that cats and dogs are
attracted by the ethylene gl ycol antifreeze, and are quite likely to drink any that
is left in an uncovered container or in puddles on the ground. This will prove
fatal in sufficient quantity. Always drai n the coolant into a sealable container.
Coolant should be reused unless it is contaminated or several years old.
