Fuse

INFOID:0000000003131921

• If fuse is blown, be sure to eliminate cause of malfunction 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 prop-

erly.

• Remove fuse for “ELECTRICAL PARTS (BAT)” if vehicle is not

used for a long period of time.

Fusible Link

INFOID:0000000003131922

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 malfunc-
tion.

• Never wrap outside of fusible link with vinyl tape. Important:

Never let fusible link touch any other wiring harness, vinyl or
rubber parts.

Circuit Breaker

INFOID:0000000003131923

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 temper-
ature 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.
