(AVV) - pin 50 - the solenoid winding is energized - pin 50 - for
the starter motor

in the engine compartment junction
unit

.
Pin 30 of
A20
, the actual starter
motor, receives the voltage coming directly from the battery A1.

, passing
through the motor

.
When the alternator does not turn, and so
does not recharge the battery, an earth signal is sent from pin

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
