Early production units were equipped with a plug-in type
rectifier that plugged into the top side of the stator
(Figure 2.47).
The bridge rectifier shown in Figure 2.48 is retained in a slot
in the generator’s rear bearing carrier.
Stator excitation winding (AC) output leads connect to the
two terminals indicated by an “E”.Wire # 4 from the
positive (+) brush connects to the terminal indicated by a
(+). Brush lead # 1 connects to the (-) terminal.
More recent units are equipped with a rectifier and brush
holder assembly, shown in Figure 2.49.
Stator excitation winding (AC) output leads connect to the
two terminals labeled J1 and J2 located on top of the bridge
rectifier.
Figure 2.50 represents a revolving field (AC) generator with
a bridge rectifier.
