DescriptionThe ignition and recharging circuit comprises a battery, starter motor and alternator.The starter motor consists of a direct current motor supplied by the battery and an excitation solenoid. When the ignition key is turned to the extreme position (AVV) [START], the starter motor windings are supplied, producing electro-magnetic forces which rotate the motor pinion. At the same time, the solenoid is energized and operates the mechanism for engaging the pinion in the flywheel ring gear, thus turning over the engine.In this version with robotized gearbox, the enablement for rotation of the starter motor is supplied by the Selespeed control unit. [E7051].The alternator recharges the battery during normal engine rotation. The alternator shaft (rotor) is turned by the crankshaft by means of a belt. When supplied with an excitation current, the rotor generates a magnetic field that induces an alternating current in the fixed winding (stator). A diode rectifying bridge located on the back of the alternator transforms the alternating current into a direct current, which is sent to recharge the battery.A voltage regulator, also built into the alternator, maintains a constant voltage supply (about 14V) throughout the load and engine speed ranges.The efficiency of the recharging system is controlled by the Body Computer, which measures the D+ signal coming from the alternator with the engine running (rpm over 700).If a fault is detected, the relevant warning light on the instrument panel is switched on.The Body Computer also acquires the battery voltage value in the 6-18V field. The information is then supplied to the CAN network for the controls unit node on the door which excludes some services in the case of a voltage drop (for example 3360775SeeE2510COURTESY LIGHTS .
Functional description When the ignition key is turned in the switch H1 to the extreme position (START) - pin 50 - the winding of the solenoid - pin 50 - of the starter motor A20 is supplied. This supply comes from the battery via the line of the maxifuse CVM of B99 and fuse F3 of the engine compartment unit B1 and sent to pin 76 of connector B of M54 (start-up request signal). However, start-up only occurs in the presence of an enablement signal - from pin 42 of connector A of the SELESPEED control unit M54 . This excites start-up enablement relay T20 located in engine bay control unit B1 : the relay - supplied with ignition on (15/54) from a line protected by fuse F16 of B1 - sends a power supply to pin 50 of starter motor A20 ; The supply controlled by the ignition (15/54) reaches pin 28 of connector A of M543361153SeeE7051ROBOTIZED GEARBOX . Pin 30 of A20 , the actual starter motor, receives the voltage coming directly from the battery A1 . The direct current generated by the alternator A10 (pin B+) is sent to the battery A1 through motor A20 . When the alternator does not turn, and so does not recharge the battery, an earth signal is sent from pin D+ to the Body Computer M1 - pin 19 of connector A: this is connected via the CAN line to the instrument panel E50 and manages, as described above, the switching on of the recharging warning light on the instrument panel.
