Abstract
A system for recharging a battery includes a current generator, a switch operable by a key and connected to the battery, an indicator lamp connected in series with the switch, and a voltage regulator with first and second inputs connected to the output of the generator and to the lamp, respectively. The regulator includes a circuit for regulating the current supplied to the field winding of the alternator in dependence on the voltage supplied by the generator, a supply circuit for supplying the voltage regulator circuit, and control circuit for enabling the supply circuit to operate when a current is flowing in the lamp and when the generator is in operation. The control circuit includes a comparator connected to the second input of the regulator, and hence to the lamp, and adapted to supply an enabling signal to the supply circuit when the voltage at the second terminal exceeds a predetermined threshold.
