2401158 - E5010 STARTING AND RECHARING - Functional description

Functional description

When ignition switch H1 is turned to the extreme position (AVV) - pin 50 - the solenoid winding is energized - pin 50 - for the starter motor A20 . This supply comes directly from the battery via the line for the fuse F3 in the engine compartment junction unit B1 . 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 , passing through the 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.
