  • fuse amere ratingWhen replacing blown fuses, make sure to use the same ampere rating fuse. The fuse rating is written on the fuse. You can verify that you are using the correct fuse, by making sure the fuse colors for the blown fuse and the new fuse match. This indicates the same ampere rating.
  • Make sure to properly close the fuse box cover and lock the tabs properly. This is very important to avoid any moisture getting inside the fuse box. The fuse box panel has a seal that is designed to keep water and moisture out of the box.
