The system includes a current generator including an alternator and an associated rectifier whose output is connected by a cable to a terminal of a battery. A switch is connected to that terminal of the battery and an indicator lamp connected in series with the switch is switched on when no current is supplied by the generator. A voltage regulator is connected to the field winding of the generator and has first and second inputs connected to the output of the generator and to the lamp respectively. The voltage regulator includes a control circuit for monitoring the potential difference between the first and second inputs of the voltage regulator and for switching on the lamp if that potential difference is greater than a pre-established reference value when the generator is operating. This enables any interruption of the connection between the generator and the battery to be indicated to the user.
