If a Fuse Blows
Used Fuses Characteristics
When an electrical device is not functioning, check that the corresponding fuse is in proper working order (intact).
A Fuse intact
B Fuse blown
On the vehicle are mainly used with mini-and maxi-fuses with blade engagement.
Besides these, there are other types of fuse provided with holes for fixing the cable connection terminals. For the replacement of these fuses contact an Authorized Maserati Dealer.
Replace the faulty fuse with a new one featuring the same rating, by using appropriate forceps.
The color identifies the value of the fuses in amperes which is also reported on them.
The table shows the match between colour and amperage of mini and maxi fuses.

Position of Fuses
The fuses are located in three parts of the vehicle, namely:
- inside the fuse and relay boxes, in the front luggage compartment, under a central cover;
- on the body computer, behind the passenger’s footrest, under the dashboard;
- inside the fuse and relay boxes located in a covered area, behind the left cover of the engine compartment.
Fuse Boxes under the Front Luggage Compartment
- To access the box it is necessary to lift the front hood (see “Access the Luggage Compartments” in the section “Before Driving”).
- To access the fuses, remove the cover in the luggage compartment, then remove the module cover unhooking the lateral locks as shown in the picture. To recognize the reference number of the fuses in the table below, see the diagram inside the cover just removed.
The table points out the position as featured in the cover, the type and function of the fuses included in the box.
CAUTION!
- After replacement, refit the protective cover of the module.
- If you need to wash the engine compartment, do not direct the water for too long directly on the module.

Fuse Boxes in the Engine Compartment
These boxes are located in an internal area that can be accessed only by removing the left engine compartment cover. Considering the complexity of this operation, we recommend having the fuses replaced by an Authorized Maserati Dealer.

How to replace a Fuse in Maserati MC20 Fuse 2022
- Seek out the fuse box:
- As for where the switch box is in the Maserati MC20, it can be under the dashboard on the driver’s side, under the hood near the battery, or even in the trunk.
- Find the blown fuse:
- Once you’ve found the fuse box, open it. There are several fuses inside, which are different sizes and colours. The fuse that blew needs to be found. A lot of fuse boxes have a picture on the lid or inside the cover that shows what each fuse does.
- Take out the blown fuse.
- Carefully grab the blown fuse with a fuse puller tool or a pair of needle-nose pliers and pull it straight out.
- Replace with a New Fuse
- Slide a new fuse with the same amp value into the empty slot. Make sure it’s firmly in place.
- Close the Fuse Box:
- Do not open the fuse box again until you are sure it is closed firmly.
- Test the Component:
- Turn on the key (or start the car if you have to) and make sure the part that goes with the new fuse is working properly by testing it.
- Don’t forget these other tips
- If a fuse blows, you should always change it with a new one of the same rating (amperage). Using a fuse with a different grade than the one it’s supposed to protect against can damage your car or mess up the electricity.
- Check Other Fuses:
- If you changed a fuse because of a problem, you should also check other fuses in that system. If there’s a bigger problem, more than one switch may blow at the same time.
