The Alfa Romeo 145 and 146 are three- and five-door small family hatchbacks produced by the manufacturer from 1994 to 2001. Built on the Fiat Type Two (Tipo Due) platform alongside the Fiat Bravo and Brava, they were marketed concurrently as premium variants. This article provides detailed fuse box diagrams for the Alfa Romeo 145/146 (930 series) covering model years 1994 through 2001.
Below are the locations and photographs of the electrical distribution boxes. Fuses for the “Cigarette lighter” and “Fuel pump” are highlighted in bold.
