Abstract
To simplify connection of a starter motor to a 24V supply with a normal on-board network of 12V, an auxiliary rectifier and an auxiliary battery are connected in parallel to the output of an automotive alternator. The starter relay switch contacts are so arranged that, only upon operation of the starter switch, the two batteries are connected in series and then to the starter motor. The supply connections to the batteries are left undisturbed, feedback being prevented by the rectifiers which are connected to the output of the alternator.
