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

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
unit

through
which

current
flows

should
not
come

into
contact
with

other
metal

parts

No

erroneous
connection
should
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

Cables
should
be

damped
so
that

they
do
not
come

into
contact
with

sharp
corner
or

part
lernperature
of

which

rises

highly

7
Cables
should
be

securely
clamped
in

posItions

sufficiently
separated
from

rotating
parts
such
as
fan

pulley
fan
belt

etc

8
Cables
should
be

provided
with
an

optimum
extra

length
at
sections

stationarity
on
the

body
or
at
sections

where
vibration

occurs
due
to

engine
operation
and

others

Note
a
When

inspecting
or

performing
other
mainte

nance

service
and
no

power
supply
is

required

particularly
or
when
it
is

anticipated
that
a

part

may
be
short
circuited
disconnect
the

battery

b
In
no
event
should
an
unloaded
circuit
be

directly
connected
with

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
