INSTRUCTIONS

Fuse

The
fuse

block
is
installed

under

the

instrument

panel
on

driver
s
side

When
for
one
reason
or
another

fuse
has
melted
use

systematic
proce

dure
to

check
and
eliminate
cause
of

problem
before

installing
new

fuse

Note

a
If

fuse
is
blown
be
sure

to
elimi

nate
cause
of

problem
before
in

stalling
new
fuse

b
Use

fuse
of

specified
rating
Never

use
fuse
of
more
than

specified

rating

c
Check
condition
of
fuse
holders
If

much
rust
or
dirt
is
found
thereon

clean
metal

parts
with

fine
grained

sandpaper
until

proper
metal
to

metal
contact
is

made

Poor

contact
in

any
fuse
holder
will

often
lead
to

voltage

drop
or

heat

ing
in

the
circuit
and
could
result
in

CAUTION

a
If
fusible
link
should
melt
it
is

possible
that
critical
circuit

power

supply
or

large
current

carrying

circuit
is
shorted
In
such
a
case

carefully
check
and

eliminate
cause

of

problem

b
Never

wrap
periphery
of
fusible

link
with

vinyl
tape
Extreme
care

should
be
taken
with
this
link
to

ensure
that
it
does
not
come
into

contact
with

any

parts

A
melted
fusible
link

can
be

detect

ed
either

by
visual

inspection
or

by

feeling
with

finger
tip
If
its

condition

is

questionable
use
circuit
tester
or

test

as

required
to

conduct

test
This

can
be

performed
