How to replace a fuse in the 2020 Maserati Granturismo Sport
- Find the fuse box.
- The fuse box is usually in the engine area or under the dashboard on the driver’s side of most cars, including the Maserati GranTurismo Sport.
- Find the fuse that is not working:
- To find the fuse that controls the broken part, look at the diagram on the cover of the fuse box. Fuses are usually labelled with a number or symbol that goes with the role they serve.
- Turn Off the Ignition:
- To avoid crashes, it’s important to turn off the ignition and take the key out of the ignition switch before working on electrical parts.
- Take out the fuse.
- If there is a fuse puller tool in the fuse box, use it. If not, you can carefully grab the fuse with needle-nose pliers and pull it out. Be careful not to hurt the fuse or the box that holds the fuse.
- Check the Fuse:
- To find out if the fuse is broken, look at it or use a multimeter. You can tell a fuse has blown because the link is broken and the metal strip inside is cut.
- Install a new fuse with the same power rating.
- Once you’re sure the old fuse is broken, install the new one. To avoid electrical damage or fire risks, it’s important to use a fuse with the right grade.
- Test the Component:
- Once the fuse is replaced, turn on the engine and test the part to make sure it works right.
- Close the Fuse Box:
- Once the part has been replaced and tested, make sure the fuse box is firmly closed to protect the fuses and keep them in place.
