Fuses, Fusible Links & Circuit Breakers

Print


CAUTION
Do not replace blown fusible links with standard wire. Only fusible type wire with Hypalon insulation can be used, or damage to the electrical system will occur!

A number of fusible links are used on these vehicles to protect wiring and electrical components. There is a collection of fusible links located near the battery. These are referred to as the main fuse links. A second group of links are located in the box with the dedicated fuses. If replacement of a fuse link is required, use the exact same link as removed.

When a fusible link blows it is very important to find out why. They are placed in the electrical system for protection against dead shorts to ground, which can be caused by electrical component failure or various wiring failures.


CAUTION
Do not just replace the fusible link to correct a problem!

When replacing all fusible links, they are to be replaced with the same type of prefabricated link available from your vehicle manufacturer.

Circuit Breakers



Resetting & Replacement

Circuit breakers are located inside the fuse panel. They are automatically reset when the problem corrects itself, is repaired, or the circuit cools down to allow operation again.

Fuses are located either in the engine compartment or passenger compartment fuse and relay panels. If a fuse blows, at least one, but possibly several components/circuits will not function properly.

  1. Remove the fuse box cover.
  2.  
  3. Inspect the fuses to determine which is faulty.
  4.  
  5. Grasp the fuse and remove it from the fuse box.
  6.  
  7. Inspect the box terminals and clean if corroded. If any terminals are damaged, replace the terminals.
  8.  
  9. Plug in a new fuse of the same amperage rating.
  10.  


WARNING
Never exceed the amperage rating of a blown fuse. If the replacement fuse also blows, check for a problem in the circuit.

  1. Check for proper operation of the affected component or circuit.
  2.
