If fuse is blown, be sure to eliminate cause of
problem before installing new fuse
Use fuse of specified rating. Never use fuse of
more than specified rating
Do not install fuse in oblique direction, always
insert
it into fuse holder properly
Remove fuse for clock if vehicle
is not used for
a long period of time.
A melted fusible link can be detected either by
visual inspection or by feeling with finger tip If its
condition is questionable, use circuit tester or test
lamp
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, care-
fully check and eliminate cause
of problem
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 con-
tact with any other wiring harness or vinyl or
rubber parts
