Checking and Replacing Fuses

To check or replace a fuse in the under-hood fuse box:

1. Locate the fuse panel in the engine compartment.

2. Remove the fuse panel cover carefully.

3. Use the fuse puller tool (usually located in the fuse panel) to remove the suspect fuse.

4. Check the fuse for any signs of damage or a broken metal strip.

5. If the fuse is blown, replace it with a new fuse of the same amperage rating.

Important: Never replace a blown fuse with one that has a higher amperage rating, as this can cause electrical system damage or even fire.

Color Coding

Ford uses a color-coding system for fuses to help identify their amperage rating:

  • Red: 10 amp
  • Light Blue: 15 amp
  • Natural: 20 amp
  • Light Green: 30 amp

This color coding helps in quickly identifying and replacing fuses with the correct amperage.

Conclusion

Understanding the 1997 Ford Ranger's under-hood fuse box diagram is essential for troubleshooting electrical issues and maintaining your vehicle. Always refer to your owner's manual for the most accurate and up-to-date information specific to your vehicle model and year.
