The fuse panel is located on a bracket on the driver's side of the instrument panel or, on some RV models it is located on a bracket attached to the brake pedal.
If a fuse blows, the cause should be investigated and corrected before the installation of a new fuse. This, however, is easier to say than to do. Because each fuse protects a limited number of components, your job is narrowed down somewhat. Begin your investigation by looking for obvious fraying, loose connections, breaks in insulation, etc. Use the techniques outlined at the beginning of this section. Electrical problems are almost always a real headache to solve, but if you are patient and persistent, and approach the problem logically (that is, don't start replacing electrical components randomly), you will eventually find the solution.
Each fuse block uses miniature fuses (normally plug-in blade terminal-type for these vehicles) which are designed for increased circuit protection and greater reliability. The compact plug-in or blade terminal design allows for fingertip removal and replacement.
Although most fuses are interchangeable in size, the amperage values are not. Should you install a fuse with too high a value, damaging current could be allowed to destroy the component you were attempting to protect by using a fuse in the first place. The plug-in type fuses have a volt number molded on them and are color coded for easy identification. Be sure to only replace a fuse with the proper amperage rated substitute.
A blown fuse can easily be checked by visual inspection or by testing for continuity.
See Figure 3
- Locate the fuse for the circuit in question.
When replacing the fuse, DO NOT use one with a higher amperage rating.
- Check the fuse by pulling it from the fuse block and observing the element. If it is broken, install a replacement fuse the same amperage rating. If the fuse blows again, check the circuit for a short to ground or faulty device in the circuit protected by the fuse.
- Continuity can also be checked with the fuse installed in the fuse block with the use of a test light connected across the 2 test points on the end of the fuse. If the test light lights, replace the fuse. Check the circuit for a short to ground or faulty device in the circuit protected by the fuse.
