FUSES
WARNING
When replacing a blown fuse, always use an appropriate replacement fuse with the same amp rating as the original fuse. Never replace a fuse with another fuse of a higher amp rating. Never replace a blown fuse with metal wires or any other material. Failure to use proper fuses may result in serious personal injury, fire, and/or property damage.
Before replacing a fuse, make sure that the ignition is off and that all the other services are switched off and/or disengaged.
If the replaced fuse blows again, contact an authorized dealer.
If a general protection fuse for safety systems (air bag system, braking system), power unit systems (engine system, gearbox system), or steering system blows, contact an authorized dealer.

FAQ’s
A: The fuse box is typically located in the engine compartment for easy access.
A: A blown fuse can often be identified by a visible break in the wire inside the fuse, but you can also use a fuse tester to check for continuity.
A: If you find a blown fuse, replace it with a new fuse of the same amperage rating. Consult the owner’s manual or fuse box cover for guidance.
A: It’s not recommended to use a fuse with a higher amperage rating, as it could lead to electrical system damage. Always use the correct amperage fuse.
A: Fuses should be checked during routine maintenance, and any blown fuses should be replaced immediately.
A: Fuses protect various electrical systems, including lights, power windows, audio, and more. The owner’s manual or fuse box cover provides details.
A: Alfa Romeo vehicles often come with a spare fuse set in the fuse box or storage compartment. Check your owner’s manual for its location.
A: The interior fuse box is typically located under the dashboard on the driver’s side. You may need to remove a cover or panel to access it.
A: With the ignition off, insert the fuse tester into the fuse socket. If the tester lights up on both sides of the fuse, the fuse is functional. If it lights up on one side but not the other, the fuse is blown.
A: Fuses are designed to be replaced, not repaired. Always replace a blown fuse with a new one of the same amperage rating.
A: Safety systems may have dedicated fuses. Consult the owner’s manual for information on specific safety-related fuses.
A: Labeling fuses in the fuse box can be helpful for quick identification. Ensure the labels are clear and accurate.
A: Alfa Romeo vehicles often have automatic resetting circuit breakers. If a circuit trips, it should reset automatically when the fault is corrected.
A: Make sure the interior fuse box cover is securely in place to prevent moisture from entering. If it’s damaged, replace it to maintain a watertight seal.
A: When handling fuses, ensure the vehicle is turned off. Avoid touching both sides of a fuse at the same time to prevent electrical shocks, and always use a fuse puller if provided for safe removal.
