POWER SUPPLY ROUTING CIRCUIT

• 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 properly.
• Remove fuse for “ELECTRICAL PARTS (BAT)” if vehicle is not used for a long period of time.

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.

1	: Fusible link

■ 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 malfunction.
  
• Never wrap outside of fusible link with vinyl tape. Important: Never let fusible link touch any other wiring harness, vinyl or rubber parts.
  

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.
