INSPECTION

Referring
to
the

wiring
diagram
check
the

wiring

harness

for
connection
with
electrical

equipment
and

connector
for
conned
ion
and
installation
When

checking

the

wiring
harness

note
the

following
matters

Connected
unit
should

not
be

loose
rusted
or

contaminated

2

Cable
insulator
cover
should
not
be

damaged
crack

ed
or

insulating
material

should
not
be
deteriorated

For
those

parts
which

are

grounded
through
the

installation

bolts
the
bolts
should
be
in
contact
with
the

body
completely
so
that

continuity
is

provided
in

between
the

body
and
bolts

4
Terminals

of

be

present

DESCRIPTION

When
an
overcunent

exceeding
the
rated

amperage

flows
to
a
circuit
the

fuse
is
heated
and
melted
the

circuit
is

interrupted
and

thus
cables
and

electrical

equipment
are

protected
from

damaging
due
to

burning
or

damaging
is

limited
to
the

minimum
This
vehicle

is

equipped
with
six

fuses
and

one
fusible
link
The
fuses

are

located

in
the

fuse
box
and
used

to

protect
illumination

signal
and
other

systems
and
the
fusible
link
is

adopted

in
the
cable
between
the

battery
and
alternator
to

protect

the

charging
and

starting
circuits

so
that

they
do
not
come

into

Cables
should
be

INSPECTION

In
the

most

cases
fuse
can
be

checked

visually

However
when

it
is
difficult
to

check

visually
a
circuit

tester

may
be
used

The
fusible
link
can

be

inspected

visually
or

by

feeling
on

finger

tip
However
the
fusible

link
can
be

inspected
more

correctly

by
using
a
circuit

tester

With

inspect
the

position
of

placing
a
mirror
at

tion

The
correct
condition
of
valve
is
that
it

keeps
the

of
underhood

open
and
that
of

closed

Otherwise

inspect

The

keeps

underhood
air
inlet
closed
when
the

passage
in

the
hose

is

stopped
by

When

through

Checking
of

I
Perform
the

engine
test

by
keeping
the

temperature

around
the

sensor
below
300C
860F
Make

sure
that

the

engine
is
cooled
down

before
the
test
is
conducted

Before

starting
the

engine
make
certain
that
the

valve

on
underhood
air
side

fully
opens

3
Start
the

engine
and

operate
it

at
an

idling
speed

The
valve
is
in

good
condition

if
underhood
air
side

fully
closes

immediately
after

starting

Carefully
watch
the
valve

to
ascertain
that

it

gradually
begins
to

open
as
the

engine
warms

up
But

when
the
ambient

temperature
is
low
it
takes

con

siderable

length
of
time

for
the
valve
to

begine
to

open

or
in
some
case
it

hardly
opens
This
should

not

however
be

regarded
as
trouble

If
the
valve
does

not

operate
satisfactorily
or
if
the

condition
of
the
valve
is

questionable
further
conduct

the

following
test

Remove
