323000759 - E1010 POWER SUPPLY SYSTEM - DESCRIPTION

DESCRIPTION

The electrical system is designed to ensure the highest possible safety levels for the vehicle and its occupants, preventing fire hazards and other consequences of electrical malfunction.Power is distributed via the junction units. These are connected to control elements (relays and static actuators) to ensure maximum electrical protection and minimum wiring complexity.The main safety solutions adopted are as follows:- the layout of the whole system is optimised to reduce the risk of damage in the event of faults or accidents;- wiring installation has been optimised to reduce incorrect positioning and noise due to vibrations- all wires offer high resistance to abrasion;- the wires in the engine compartment are specially designed to be resistant to high temperatures and are protected by sheaths or piping;- the wires in the passenger compartment are protected by corrugated pipes and napped tape to reduce noise levels;- the main connections come with secondary lock terminals and lever locks or CPA to prevent terminal deformation.All systems and electrical equipment are supplied by the battery at a voltage of 12V.The battery is, in turn, recharged by the alternator during engine operation.    See E5010 STARTING AND RECHARING 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 MAR. This supplies numerous circuits that are described as ignition-operated (INT and 15/54 lines);- the second click - AVV position - supplies the starter motor (line 50). Other circuits (those that absorb most power) are disconnected to ensure maximum current flow to the motor (INT/A line).

The lines that distribute power to the various appliances are represented by wiring diagrams for the various functions and systems.This general diagram shows all the lines as they leave the battery. Refer to specific diagrams for more details.
