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 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.
