Alfa Romeo 145 and 146 fuse box and relay Diagrams (1994-2000)

The Alfa Romeo 145 and 146 were two small family cars produced by the Italian automaker Alfa Romeo between 1994 and 2000. The cars were available as three and five-door hatchbacks and were designed by Walter de Silva, who later went on to design the Audi R8 and Lamborghini Gallardo. The Alfa Romeo 145 and 146 were popular for their sporty driving experience and distinctive Italian styling.

As with any car, the Alfa Romeo 145 and 146 had various electrical components that were essential to the functioning of the vehicle. One of the key components in the electrical system of these cars is the fuse box and relay. In this article, we will explore the fuse box and relay of the Alfa Romeo 145 and 146, and the importance of these components in the overall performance of the car.

The Fuse Box of the Alfa Romeo 145 and 146

The fuse box of the Alfa Romeo 145 and 146 is located in the dashboard on the driver’s side of the car. It contains fuses that protect the electrical system of the vehicle from overloading and short-circuits. The fuses are made of a metal wire that melts when it is exposed to an excessive electrical load, thereby breaking the circuit and protecting the electrical components from damage.

It is essential to ensure that the correct type of fuse is used when replacing a blown fuse in the Alfa Romeo 145 and 146. The owner’s manual of the car provides information on the correct rating of fuses to be used in each circuit. Using a fuse with a higher rating than recommended can result in damage to the electrical components, while using a lower rating can cause the fuse to blow prematurely, resulting in a loss of power to the affected circuit. Regular inspection and replacement of faulty fuses is important to ensure the proper functioning of the electrical system.

The Relay of the Alfa Romeo 145 and 146

The relay of the Alfa Romeo 145 and 146 is an electrical component that acts as a switch for various systems in the car. It is responsible for controlling the flow of electricity to the different circuits in the car. The relay works by using an electromagnet to activate a set of contacts, which then allows electricity to flow through the circuit.

One of the critical relays in the Alfa Romeo 145 and 146 is the starter relay, which is responsible for starting the car’s engine. It is located in the engine compartment and is activated by the ignition switch. Other relays in the car include the fuel pump relay, cooling fan relay, and horn relay, among others.

For 1.9 JTD engine on a special bracket under the passenger’s side floor trim, in correspondence with the injection control unit, there is a set of fuses and relays.

For versions/markets where applicable, for the 1.9 JTD engine, the following relays are to be found in the correspondence of the right headlamp:

• — Additional passenger compartment heater relay 1^st level
• — Additional passenger compartment heater relay 2^nd  level
• — Additional heater safety switch,

In addition, only for versions with air conditioners, on the engine fan duct, there is a switch for the engine fan’s 2^nd speed.

In conclusion, the Alfa Romeo 145 and 146 were iconic small family cars that were popular for their sporty driving experience and distinctive Italian styling. However, like any car, these vehicles had various electrical components that were essential to their performance. The fuse box and relay are two critical components of the electrical system, and it is crucial to ensure their proper functioning through regular inspection and replacement of faulty parts.
