The Chevrolet Beretta (1987-1996) is known for its sporty design, reliable V6 engine options, and front-wheel drive, offering a smooth driving experience. Key features include a comfortable interior, power windows, and an advanced-for-its-time stereo system, all dependent on the vehicle’s electrical system.
The fuse box, located under the dashboard and in the engine compartment, protects critical components like the lights, wipers, and radio by cutting off power in the event of an electrical overload. Blown fuses need to be replaced to restore functionality to these systems.
The relays in the Beretta control essential functions such as the fuel pump, cooling fan, and starter motor. These relays act as switches to manage the flow of electricity to high-power components. A faulty relay can lead to issues like the car failing to start or overheating due to a non-operational fan.
Maintaining the fuse box and relays is crucial to keeping the Beretta’s systems running smoothly, ensuring all electrical components remain functional and protected from damage.

WARNING
- Never replace a fuse with one that has a higher amperage rating.
- A fuse with a too-high amperage could damage the electrical part and cause a fire.
- On no account should fuses be repaired (e.g. patched up with tin foil or wire) as this may cause serious damage elsewhere in the electrical circuit or cause a fire.
- If a fuse blows repeatedly, do not keep replacing it. Instead, have the cause for the repeated short circuit or overload tracked and fixed.
- Terminal and harness assignments for individual connectors will vary depending on vehicle equipment level, model, and market.
