2892609 - E5010 STARTING AND RECHARING - Functional description

Functional description

When the ignition key for the switch H1 is turned to the extreme position (AVV) 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 recharge the battery A1 , passing 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 1 of connector C. The instrument E50 is supplied with the ignition switched on (INT) at pin 2 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.
