POWER SUPPLY DESCRIPTION

Description

The electrical system is designed to increase the car''s safety level and prevent the possibility of fires and other consequences of electrical malfunctions. State-of-the-art connectors have been introduced to rule out the possibility of many connection defects.

Power is distributed via the junction units and/or fuses boxes. These are connected to control elements (relays and static actuators) to ensure maximum electrical protection and minimum complexity.

The main safety solutions adoptd are as follows:

• power supplies protected by maxifuses to cut off the electrical system, in the case of short circuit, immediately downstream of the battery (see detail below);
• the layout of the whole system is optimised to reduce the risk of damage in the case of faults or accidents.
• wiring installation has been optimised to reduced incorrect positioning and noise due to vibrations;
• all wires offer high resistance to abrasion
• the wires in the engine are of special type, resistant to high temperature and protected with piping sheaths.
• wires in the passenger compartment are protected by corrugated pipes and felted tapes to reduce noise levels
• the main connections coem with secondary lock terminals and lever locks to prevent terminal deformation.

All systems and electrical equipment are supplied by the battery at a voltage of 12V.

The battery is recharged by the alternator during engine operation

See E5010 STARTING AND RECHARING

Some of the power supply lines are protected by MAXIFUSES grouped together in a casing located next to the battery and directly connected to it.

Other fuses are grouped together in an additional fuse box, located near the maxifuses.

The other fuses (MAXI and "normal") and the various relay feeds are located in the engine compartment junction unit and directly inside the body computer.

Some circuits are continuously supplied, even with the car at a standstill and the key out because they are connected directly to the battery.

Other circuits are supplied by turning the ignition key to various positions:

• insert the key and turn it through one click to position M. This supplies numerous circuits that are described as ignition-operated

• the second position - D - supplies the starter motor.
