PROBLEM TO BE SOLVED: To feed power necessary for engine control at starting even when battery charge is insufficient and so on. SOLUTION: Two coils L1, L2 are arranged to an AC generator 1, a positive voltage output of the coil L1 is used for battery charging, the negative voltage output thereof is used for driving a lamp 6, and an output of the coil L2 is used for engine control loads 12, 13 by being full-wave rectified by a full-wave rectifier 11. A transistor FET 1 is arranged between a charging terminal 2b of the battery and the rectifier 11, and controlled by a control circuit 9. A power supply capacity necessary for the engine control load can be supplied by only the second coil. In a small-sized motorcycle that is started by kicking when the battery charge is insufficient, since all of the outputs of the second coil can be used for an engine control system, sufficient power can be fed to the engine control load even by the kick starting.
