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 speci-
fied rating.
c. Do not install fuse in oblique direction; always insert it into fuse
holder properly.
d. Remove fuse for clock if vehicle is not used for a long period
of time.
Fusible Link
A melted fusible link can be detected by visual inspection. If its
condition is questionable, use circuit tester or test lamp.
CAUTION:
IIf 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.
INever wrap periphery of fusible link with vinyl tape.
Extreme care should be taken with this link to ensure that
it does not come into contact with any other wiring har-
ness or vinyl or rubber parts.
Circuit Breaker Inspection
For example, when current is 30A, the circuit is broken within 8 to
20 seconds.
CIRCUIT BREAKER (PTC THERMISTOR TYPE)
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 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.
