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.

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 tem-
perature to rise. When the temperature reaches a specified level,
the electrical resistance will rise sharply to control the circuit cur-
rent.
Reduced current flow will cause the element to cool. Resistance
falls accordingly and normal circuit current flow is allowed to
resume.
