How to replace a 2018 Maserati Granturismo MC fuse
- Turn off the Engine
- It’s important to turn off the engine and take the key out of the ignition before working on any electrical parts.
- Find the fuse that has blown
- If you’re not sure which fuse is blown, look at all of them. Often, a broken wire will be inside a fuse that has blown.
- Take out the blown fuse.
- To do this, use a fuse puller tool or needle-nose pliers to carefully grab the blown fuse and pull it straight out of its hole. Don’t use too much force, or you could damage the fuse or the box that holds the fuse.
- Put in the New Fuse
- Pick up a new fuse with the same grade and put it in the empty fuse socket. To make sure a safe link, make sure it’s in.
- Check for Tightness
- Once the new fuse is in the socket, give it a light tug to make sure it’s in there properly and securely.
- Test the Component
- Once you’re done changing the fuse, put the key in the “accessory” position on the ignition (without starting the engine) and test the part that goes with the new fuse. You’ve successfully changed the fuse if it’s working right.
- Replace the cover on the fuse box.
- If necessary, replace the cover on the fuse box and make sure it fits firmly.
- Get Rid of Old Fuse
- Get rid of the blown fuse the right way. You can always use the extra fuse in your fuse box as a backup, but it’s important to change it as soon as possible.
- Close the Hood
- If you go to the switch box in the engine bay, make sure the Maserati’s hood is safe.
