DESCRIPTION - STARTING AND RECHARING - Fiat GRANDE PUNTO 1.2 8v
The ignition and recharging circuit comprises the battery, starter motor and alternator.The starter motor consists of a d.c. motor supplied by the battery and an excitation electromagnet.With the alternator still with the ignition key in the ON position, the warning light in the instrument panel comes on and sends a power supply to the voltage regulator built into the alternator via terminal D+.In these conditions the energizing circuit (rotor) is enabled to earth by the regulator electronics.With the alternator rotating through the effect of the variation of the rpm and the magnetic field, a three-phase alternating voltage is produced in the electrical circuit (stator) which rectified by the diode bridge can exit terminal B+.When the upper fixed calibration level (13.7 - 14.2 V) is reached it charges the battery and supplies the system.The engine control unit and Body Computer monitor the efficiency of the recharging system:- the engine control unit sends signal D+ to the Body Computer that monitors the efficiency of the alternator recharging system by recording two parameters: the voltage signal from alternator terminal D+ and the engine rpm signal that also receives signals from the engine control unit via the CAN.- at key-on while the voltage is less than approx 5.5V, the Body Computer indicates that recharging is insufficient; when the voltage exceeds 5.5V, the warning light goes off. If - with the engine running (rpm higher than 700) - the voltage drops below a threshold of 4.5 V, the warning light comes on in fixed manner, accompanied by a message on the display.
FUNCTIONAL DESCRIPTION - STARTING AND RECHARING - Fiat GRANDE PUNTO 1.2 8v
The Body Computer M1 - connector G - is supplied directly from the battery from a line protected by maxifuse F2 of engine compartment control unit B1. It is ignition-operated (INT) at pin 32 of connector D. Pin 10 of connector H of M1 supplies a reference earth to the Body Computer.Power distribution to the vehicle (INT "ignition-operated, INT/A, "AVV", etc) is managed by the Body Computer that is connected to ignition switch H1:- ignition switch H1 is supplied by the Body Computer from pin 48 of connector D of M1 via a line protected by fuse F85;- ignition switch H1 sends ignition-operated signal “15/54” to Body Computer M1 at pin 32 of connector D.When the ignition key H1 is turned to its furthest position (START) - pin 50 - power is sent to the electromagnetic winding - pin 50 - if starter motor A20 - in accordance with the control strategy described previously:- the ignition switch H1 sends a START signal to Body Computer M1 at pin 31 of connector D; and this in turn sends an enablement request to engine control unit M10 via the CAN;- start-up takes place only in the presence of an enablement signal - from pin 40 of connector A of engine control unit M10: this energizes the start-up enablement relay T18, located in the engine compartment control unit B1: the relay - supplied by an ignition-operated supply from a line protected by fuse F35 and relay T6 of B1: this ignition-operated supply (INT) is controlled from pin 1 of connector A of M1;- the start-up enablement relay T18 of B1 then sends a power supply to pin 50 of starter motor A20.Pin 30 of A20 - connector A - i.e. the actual motor, receives a power supply with the voltage coming directly from the battery A1.The direct current generated by alternator A10 (pin B+) - connector B - is sent to battery A1 via the MAXIFUSE box on the battery, passing through motor A20.When the alternator does not turn and does not therefore recharge the battery, an earth signal is sent from pin D+ - connector A - of A10 to engine control unit M10 - pin 19 of connector A: this is connected via the CAN line to Body Computer M1 and to instrument panel E50 and manages, as described above, activation of the generator warning light on the instrument panel.ALTERNATOR
