2892612 - E5010 STARTING AND RECHARING - Functional description (GPOWER, Euro 3, BIPOWER, BLUPOWER)

Functional description

When the ignition key for the switch H1 is turned to the extreme position (AVV) [START], the solenoid winding (pin 50) of the starter motor A20 is supplied. This supply comes from the battery via the line of maxifuse IGN of B5 . 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 is not turning, i.e. not recharging the battery, an earth signal is sent from pin D+ to instrument panel E50 - pin 8 of connector B. The instrument E50 is supplied with the ignition switched on (INT) at pin 19 of connector A from the line protected by fuse F1 of the junction unit B1 : when this signal arrives, the 'recharging' warning light comes on. When the engine has been started up, this signal becomes 12 V and the warning light therefore goes out.
