FUSIBLE LINK

NHEL0007S02

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:

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 (PTC THERMISTOR TYPE)

NHEL0007S03

The PTC thermistor generates heat in response to current flow.
The temperature (and resistance) of the thermistor 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.
