Description - POWER SUPPLY - Fiat DOBLO 1.2 8v Da 10/2000

The 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 kind involves the thoughtful design of wiring, attentive to location and anchorage, and the careful planning of properly protected cable routes.Modifications have therefore been made to the alternator and starter motor cables, with the adoption of protective caps.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] during engine operation.The main supply lines are protected by fuses grouped together ina junction unit positioned near the battery and supplied directly by it.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 - start up position - 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);].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 junction unit and the ignition switch; reference should be made to the specific diagrams for greater detail.

Functional description - POWER SUPPLY - Fiat DOBLO 1.2 8v Da 10/2000

All the electrical equipment and systems are supplied by the battery A01.The supply for the various devices is controlled by two junction control units in the engine bay B01 and under the facia B02 . These contain the fuses and the relays which allow the electrical apparatus to work properly.Other circuits are supplied by turning ignition key H01 to various different positions:In the ON position, numerous circuits and services controlled by the ignition (INT line) are supplied, protected by fuses for the junction unit B01 and (line 15/54)in the AVV position - the starter motor is supplied; (line ''50'')in the PARK position the side lights are supplied (''STAZ'' and ''POS'' lines);.
