ELECTRICAL SYSTEM 7-7
CHARGING SYSTEM
DESCRIPTION
The charging system consists of a generator, regulatorlrectifier, and battery. The AC current, which is gener-
ated by the generator, is converted by the regulatorirectifier into DC current. The regulator/rectifier is one
unit with two functions. The regulator prevents overcharging of the battery by grounding the excessive
AC
current. The rectifier changes the AC current, which is produced by the generator, to the DC current.
Al l of these components work together to maintain a correct and constant voltage and to prevent the battery
from overcharging.
