Abstract
A road vehicle battery charging system includes an alternator, and a rectifier connecting the alternator across a battery. A further rectifier provides an additional d.c. output for energising the field winding of the alternator and this additional output is connected to the appropriate battery terminal via an ignition switch. A voltage sensing circuit operates to illuminate a warning lamp should the voltage on the line exceed a predetermined level.
