STARTING SYSTEM
Tbt
starling system
has
only one
function to
perform-to
crank
the
engine.
In
the starting syste.m
there
are
four basic
unit.!: the
baucry,
the
starting solenoid,
the
slarting
relay,
and
the
starting
motor.
The battery supplies
the
energy,
the
solenoid completes
the circuit,
allowing
this energy to
flow
to the starting
motor
and
the relay is used with the
Jenoid
to
reduce
the
volLage
drop
during
the
slarting
operation.
The motor which
draws
a
large
amount of Cur-
rent
rOT
a short
period
of
time, then delivers mechanical
oergy
and does
the
actual
work
of cranking
the
engine.
he
motor
is
designed
to
incorporate
a solenoid drive
echanism
which assures
positive
engagement of
lhe
start-
ng
motor
pinion with
lhe flywheel until the
engine
is
SlaTted. The
solenoid is controlled by
the key
starter
switch
D
the
battery
circuit.
A
shielded
neutral safety
switch
is
rovided
to prevent slarting
of the
engine
with the trans-
mission
selector
lever in other than
up"
or UN" position.
he
starter solenoid should
be lubricated
as
described on
page
61.
he
Corvette is equipped
with
uSealed
Beam" headlight
oilS
in
which the
light
sou1te
J
the reflector, lens and
gasket
arc all assembled in a securely sealed
unit.
This sealed
con-
struction prevents
tarnished reflectors
and keeps
dirt
and
moisture
from the reflector
and inside of
lens,
assuring
maximum Hghting efficiency throughout the
life
of
the
unit.
The
"Sealed
Beam" units
have
two
separate filaments
located
in
the
unit in position
to
produce
an
upper
(coun-
try) light
beam
and
a
lower
(traffic)
light
beam
.
The
upper
beam
is designed to iJluminate the
road evenJy for con-
siderable
distance ahead
of
the
vehicle
and
should
only
be
used
on
the
open
highway
when
no other vehicles
are
approaching.
The lower
beam is adjusted
to illuminate the
right
side
of
the road
a
reasonable distance
ahead
but to
prevent
glare
in the
eyes of
the oncoming
driven.
When the
Fig. 74-/-ltadlamp a"d
SaUrI
upper
beams
are in
USC
J
a
red
pilot light will be scen
through
a small opening
in
the
speedometer
dial. The
dimmer
swiech is
used to
switch from one beam to
the
other. A wire protector
screen, rim and
housing
as-
sembly
(fig.
74), which
is
hinged
at
the top
and se-
cured wi th a single screw
at the bottom, is
provided
