CHARGING CIRCUIT
The two basic types of charging systems are the SI integral
regulator charging system (Fig. 6E-24 and 6E-25) and the
10 DN mechanical regulator charging system (Fig. 6E-
23). The SI system is standard on all B, G A and F Series
cars. The 10 D N system is standard on the X Series. These
components are connected electrically as shown in Fig.
6E-26 and 6E-27.

GENERAL DESCRIPTION
The Delcotron generator feature$ a solid state regulator
that is mounted inside the generator slip ring end frame.
A11 regulator components are enclosed into a solid mold,
and this unit along with the brush holder assembly is
attached to the slip ring end frame. The regulator voltage
setting never needs adjusting, and no means for adjust-
ment is provided.
The generator rotor bearings contain a supply of lubricant
sufficiently adequate to eliminate the need for periodic
lubrication. Two brushes carry current through the two
slip rings to the field coil mounted on the rotor, and under
normal conditions will provide long periods of attention-
free service.
The stator windings are assembled on the inside of a lami-
nated core that forms part of the generator frame. A rec-
