Fuse AKS00BET
● If fuse is bl own , be sure to el im ina te ca us e o f mal fu nc t io n bef or e
installing new fuse.
● Use fuse of specified rating. Never use fuse of more than speci-
fied rating.
● Do not partially install fuse; always insert it into fuse holder prop-
erly.
● Remove fuse for “ELECTRICAL PARTS (BAT)” if vehicle is not
used for a long period of time.
CEL083
Fusible Link AKS00BEU
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 shou ld melt, it is possible tha t critical circuit
(power supply or l arge current carrying ci rcuit) is shorted.
In such a case, carefully check and elim inate ca use of ma lfunction.
● Never wrap outside of fusible link with vinyl tape. Import ant:
Never let fusible link tou ch any other wiring ha rness, vinyl
or rubber parts.

Circuit Breaker AKS00BEV
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.
