2020 Maserati Ghibli Fuses and Fuse Box | Checking and replacing fuses
The 2020 Maserati Ghibli has a full electrical system, and the fuses are an important part of keeping different parts safe from electrical problems or overloads. The fuse box usually sits in an easy-to-reach spot, like the kick panel on the driver’s side or under the hood. It holds several fuses, each of which protects a different circuit in the car. As part of regular upkeep, checking and replacing fuses makes sure that electrical functions work well. If something isn’t working right, a blown fuse could be the cause. The first step in fixing is to look inside the fuse box. When checking fuses, it’s important to look in the owner’s guidebook to find the fuse that goes with the circuit that isn’t working. Finding and replacing a fuse is easy; all you need is a fuse puller or pliers to take the blown fuse and put in a new one with the right amperage rating. The 2020 Maserati Ghibli electrical system is more reliable and works better when the fuses and fuse box is checked and maintained regularly.

Fuse Replacement
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 the Service Network.
Replace the faulty fuse with a new one featuring the same rating, by using appropriate forceps added in the integrated power module and inside the cover of the rear power distribution center.
The colour identifies the value of the fuses in amperes which is also reported on them.
The table shows the match between the color and amperage of mini and maxi fuses.

| Green – 30 | – |
CAUTION!
- Never replace a blown fuse with anything other than a new and suitable fuse (same rating).
- After replacing a fuse, if the fault recurs, contact the Service Network.
Position of Fuses
The fuses are located in three parts of the vehicle, namely:
- inside the integrated power module, on the right-hand side of the engine compartment;
- inside the rear power distribution center, behind the battery, on the right-hand side of the boot compartment;
- on the fuse and relay box located in a covered area, behind the glove compartment on the dashboard’s left side.
Integrated Power Module
- To access the module it is necessary to lift the hood (see “Open and Close the Hood” in the section “Before Starting”).
- To access the fuses 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, and the type and function of the fuses included in the integrated power module.
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 Box under the Dashboard
This box is located in an internal area that can be accessed only by removing the glove compartment on the dashboard’s left side. Considering the complexity of this operation, we recommend having the fuses replaced by the Service Network.
The table points out the position as featured in the figure, the type, and the function of the fuses in the box under the dashboard.

FAQs
The fuse box in the 2020 Maserati Ghibli is typically located in the engine compartment or interior cabin.
The car usually has multiple fuse boxes, with one in the engine compartment and another in the interior.
Fuses protect electrical circuits from overloads and prevent damage to electrical components in the vehicle.
Use a fuse tester or visually inspect the fuses. If the metal strip inside the fuse is broken, the fuse is likely blown.
Typically, a set of spare fuses is provided in the fuse box.
Basic tools such as a fuse puller or needle-nose pliers are usually sufficient for fuse replacement.
No, it’s important to use fuses with the correct amperage rating as specified in the owner’s manual to avoid electrical issues or damage.
The amperage rating is usually printed on the fuse.
Overloading circuits, electrical faults, or short circuits can lead to blown fuses.
Yes, a blown fuse can affect specific electrical systems, such as lights, audio, or power windows.
Ensure the vehicle is turned off, and consult the owner’s manual for safety information before replacing fuses.
Regularly inspect fuses as part of routine maintenance or when experiencing electrical issues.
No, using a higher-rated fuse can lead to electrical damage. Always use the recommended amperage.
If you’re unsure or if there are persistent electrical problems, it’s recommended to consult a professional technician.
While removing and reinserting a fuse may reset certain systems, it’s not a universal solution, and specific issues should be diagnosed and addressed appropriately.
