Fuse
a. If fuse is blown, be sure to eliminate cause of problem
before installing new fuse.
b. Use fuse of speci®ed rating. Never use fuse of more than
speci®ed rating.
c. Do not partially install fuse; always insert it into fuse
holder properly.
d. Remove fuse for ``ELECTRICAL PARTS (BAT)'' if vehicle is
not used for a long period of time.
Fusible Link
A melted fusible link can be detected either by visual inspection or
by feeling with ®nger tip. If its condition is questionable, use circuit
tester or test lamp.
CAUTION:
+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.
+Never wrap outside of fusible link with vinyl tape. Impor-
tant: Never let fusible link touch any other wiring harness,
vinyl or rubber parts.
Circuit Breaker Inspection
For example, when current is 30A, the circuit is broken within 8 to
20 seconds.
