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

CAUTION

a
If

it
is

possible
that

is
shorted
In
such
a
case

carefully
check
and

eliminate
cause

of

b
Never

wrap

can
be

detect

ed
either

by
