DescriptionThe entire electrical system has been designed and constructed in accordance with the most up-to-date guidelines concerning safety and protection, especially against fire risks.There are two main kinds of protection:active protection, aimed at reducing possible causes of faults 'at source';passive protection, aimed at minimizing the effects of a possible fault.
The first category involves careful design of wiring with thorough positioning and anchorage. Wiring is shielded and protected and the routes are carefully determined. Modifications have therefore been made to the alternator and starter motor cables, with the adoption of protective caps, etc.Passive protection instead includes all the interventions, which have always been adopted on vehicles, to reduce high fault currents (overload and short circuit).All the fuses included in the system have been rated on the basis of the nominal absorption of the loads which cannot be served simultaneously, and so as to ensure intervention in the case of a definite short circuit.All the electrical systems are supplied by the battery at a voltage of 12. V. The battery is in turn recharged by the alternator ( 2889333SeeE5010
STARTING AND RECHARING ) during engine operation. The main supply lines are protected by maxifuses, contained in two fuse boxes located near the battery and supplied directly from the latter.The power supplies for all the services and systems are protected by specific fuses, contained in the junction unit, or shunt fuses. The shunt fuses are located under the dashboard either just above the junction unit, or on the right above the glove compartment.All the power supplies are thus protected, except for the starter motor cable (battery-starter motor) and recharging cable (starter motor-alternator): these are protected by an additional shielded sheath.Some circuits are supplied continuously, even if the vehicle is stopped and the ignition is off, as they are connected directly to the battery.Other circuits are supplied by turning the ignition key to various different positions:when the key is inserted and turned to the first click, the ignition is turned on (MAR position) and several circuits are supplied, which are thus called 'ignition-operated' (lines 'INTE' and '15/54');the second click - AVV position - instead supplies the starter motor; (line '50')., disconnecting some circuits (those which absorb most power), thus ensuring the maximum flow of current to the starter motor; ('INT/A' line).on the other hand, by extracting the key and turning it in the opposite direction (and pressing the special button) the PARK position is engaged which supplies the side lights even with the key switched off ('STAZ' and 'POS' lines); (2888812SeeE2010
SIDE LIGHTS / NO. PLATE LIGHTS).
767The lines through which the supply is distributed to the various electrical devices are shown on the wiring diagrams relating to the various functions and systems.This general diagram shows all the lines which depart from the battery and the MAXIFUSE boxes; reference should be made to the specific diagrams for greater detail. Functional description All the electrical equipment and systems are supplied by the battery A1.The main supply lines are protected by the MAXIFUSE box B5 which contains the fuses named according to the circuits protected:IGN: ignition switch H1 supply;J/B2 and J/B1: supply for services through junction unit B1 fuses.
