InspectionNJEL0007FUSENJEL0007S01If 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 partially install fuse; always insert it into fuse
holder properly.
Remove fuse for “ELECTRICAL PARTS (BAT)” if vehicle is
not used for a long period of time.
SEL165W
FUSIBLE LINKNJEL0007S02A 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:
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.
SBF284E
CIRCUIT BREAKERNJEL0007S03For example, when current is 30A, the circuit is broken within 8 to
20 seconds.
SEL109W
CIRCUIT BREAKER (PTC THERMISTOR TYPE)NJEL0007S04The PTC thermister generates heat in response to current flow.
The temperature (and resistance) of the thermister element varies
with current flow. Excessive current flow will cause the element’s
temperature to rise. When the temperature reaches a specified
level, the electrical resistance will rise sharply to control the circuit
current.
Reduced current flow will cause the element to cool. Resistance
falls accordingly and normal circuit current flow is allowed to
resume.
