841006259 - E1010 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.All wiring looms have been made modular by changing the way functions are distributed inside the connectors and replacing welds with short-circuiting joints.The main safety solutions adoptd are as follows:- power supplies protected by maxifuses for the electrical system switch, in the case of short circuit, immediately downstream of the battery (see detail below);
- the only leads excluded from the maxifuses (starter motor and alternator) are located in protected areas;
- 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.
- CVM: engine compartment junction unit supply
- CVB: load compartment junction unit supply
- CPL2: underfacia junction unit supply;
- CPL1: underfacia junction unit supply;
- insert the key and turn it through one click to ON. 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 absorbe most power) are now disconnected to ensure a maximum current flow to the motor; (INT/A line)
- when the ignition is removed, the Exterior Lighting Control unit may be set to PARK to supply the side lights even with the key out ("STAZ" and "POS" lines); See E2010 SIDE LIGHTS / NO. PLATE LIGHTS
the lines used to distribute power to the various services are shown in the wiring diagrams for the various functions and systems. This general diagram shows all lines as they leave the battery and the MAXIFUSE box and the ignition key. See specific diagrams for greater detail. |
