position
In
this
inspection
the
car
must
be
placed
on
a
level
surface
The
amount
of
the
oil
varies
with
the
temperature
As
a
rule
the
oil
level
must
be
measured
after
its
tempera
ture
becomes
sufficiently
high

At

care
should
be
taken
of
to

the
oil

2
Inspecting
oil
condition
The
condition
of
oil
sticking
to
the
level
gauge
indicates
whether
to
over
haul
and
repair
the
transmission
or
look
for
the
defective
part
If
the
oil
has
deteriorated
into
a
varnish
like
quality
it
causes
the
con
trol
valve
to
stick
The
blackened
oil
gives
the
proof
of
the
burned
clutch
brake
band
etc
In
these
cases
the
transmission
must
be
replaced
Notes
a
In
oil
level
checking
use
special
paper
waste
to
handle
the
level
gauge
and
take
care
not
to
let
the
scraps
of
paper
and
cloth
tick
to
the
gauge
b
Insert
the
gauge
fully

take
it
out
quickly

To
exactly
locate
the
place
of
oil
leakage
proceeds
as
follows
Place
the
vehicle
in
a
pit
and
by
sampling
the
leaked
oil
examine
whe
ther
it
is
the
torq
le
converter
oil
or
not
The
torque
converter
oil
assumes
color
like
red
wine
when
shipped
from
the
factory
so
it
is
ea
ily
distin
guished
from
engine
oil
or
gear
oil
Cleanly
wipe
off
the
leaking
oil
and
dust
and
detect
the
spot
of
oil
leakage
Use
nonflammable
organic
solvent
such
as
carbon
tetrachloride
for
wip
ing
Raise
the
oil
temperature
by
op
erating
the
engine
and
shift
the
lever
to
0
to
heighten
the
oil
pressure
The
spot
of
oil
leakage
will
then
be
found
more
easily
Note
A
the
oil
leakage
from
the
breather
does
not
take
place
except
when
running
at
high
speed
it
is
impossible
to
locate
the
spot
of
leakage
with
vehicle
stalled
AT

Checking
engine
idling
rprn
The
engine
idling
revolution
should
be
properly
adjusted
If
the
engine
revolution
is
too
low
the
engine
does
not
operate
smoothly
and
if
too
high
a
strong
shock
or
creep
develops
when
changing

solenoid
When
the
kick
down
operation
is
not
made
properly
or
the
speed
chang
ing
point
is
too
high
check
the
kick
down
switch
downshift
solenoid
and
wiring
between
them
When
the
igni
tion
key
is
positioned
at
the
1st
stage
and
the
accelerator
pedal
is
depressed
deeply
the
switch
contact
should
be
closed
and
the
solenoid
should
click
If
it
does
not
click
it
indicates
a
defect
Then
check
each
part
with
the
testing
instruments

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

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
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

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
securely
clamped
in
posItions
sufficiently

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

CHECKING
SPECIFIC

The

by
means
of
a

the

the
battery
is
below
60

the

Checking

in

The
standard
specific
gravity
of
the
electrolyte
is
obtained
when
the
battery
is
fully
charged
at
an
electro
lyte
temperature
of
200
e
680
F
When
temperature
rises
loe
1
80F
the
specific
gravity
decreases
0

and
reversely
when
temperature
drops
loe
I
ROF
the
specific
gravity
increases
0

Therefore
assuming
the
specific
gravity
at
tOe
is
St
S20
the
specific
gravity
at
200e

is
calculated
according
