INSPECTION
Referring
to
the
wiring
diagram
check
the
wiring
harness
for

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
3
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
5
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

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

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
