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

specified rating.

c. Do not partially install fuse; always insert it into fuse holder

properly.

d. Remove fuse for “ELECTRICAL PARTS (BAT)” if vehicle is

not used for a long period of time.

Fusible Link

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 cir-
cuit (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.
Important: Never let fusible link touch any other wiring
harness 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 thermister generates heat in response to current flow.
The temperature (and resistance) of the thermister element var-
ies 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 con-
trol the circuit current.
Reduced current flow will cause the element to cool. Resistance
falls accordingly and normal circuit current flow is allowed to
resume.
