Fuse
a. If fuse is blown, be sure to eliminate cause of problem
before installing new fuse.
b. Use fuse of specified rating. Never use fuse of more than
specified rating.
c. Do not partially install fuse; always insert it into fuse
holder properly.
d. Remove fuse for ``ELEC B'' 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 finger tip. If its condition is questionable, use
circuit tester or test lamp.
CAUTION:
lIf fusible link should melt, it is possible that critical cir-
cuit (power supply or large current carrying circuit) is
shorted. In such a case, carefully check and eliminate
cause of problem.
lNever 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.
Circuit breakers are used in the following systems.
lPower window
lPower door lock
lMulti-remote control system
