of the radiator it is necessary to screw the tie rods
in or out of the anchor plates and then fasten the
front end of the rod to the radiator core.
The water pump for the 370-D and 452-D engines
is new. It is of the self-adjusting type, and is
provided with two •011116 - ' bushings amply protected
by packings to prevent water leakage and to
retain the lubricant. See Fig. 24.
The water pump is lubricated through a grease
gun fitting.
Electrical, System
The electrical system is of the same genera-l
arrangement on all the new cars except the ignition
circuits. The ignition systems are necessarily
different because of the difference in the number of
cylinders in the eight, twelve and sixteen cylinder
engines. The lighting is the same on all models.
Storage Battery
The storage batteries are the same as used on the
corresponding "C" models. The battery mounting,
however, is new. Sec Fig. 25-
' The battery on the Series 10 and 20 cars is carried
under the front seat in a hanger supported in the
X-mcmbcr of the frame. The battery on all other
wheclbase cars is carried under the right front
fender in approximately the same location as in the
"C" cars. These batteries can be reached from
under the hood for adding water.
The storage battery on the Series 10 and 20 cars
may be removed from underneath the seat. On the
longer whcelbase cars with the battery carried
under the right front fender the battery is removed
as follows: Remove battery box retaining screws
at the top of the frame and then lift the battery and
carrier assembly slightly to unlock the carrier
from the frame.
Generator
The generator is of the shunt wound current
control type. It has no third brush and no adjustment
is provided except by the lamp load through
a current regulator. In other words, the charging
rate is automatically increased when the lights are
switched on. See Figs. 26 and 27.
The general construction of the new generator is
similar to that of the series "C" generator, the
chief external difference being in the current
regulator or control. The generator has a ventilating
feature for reducing the operating temperature.
The conventional cut-out relay, the
current regulator, the field fuse and the thermostatic
circuit breaker for the head lamps are
mounted together in a control box on top of the
generator as shown in Fig. 28.
PVrf 25 The battery is located in a compartment
unde, the right front fender on 355-D Fleetwood,
370 D W 452-D cars. On the Series 10 and 20 cars
the battery is located under the front seat
The mounting and drive arc the same as on the
corresponding "C" cars. No service is necessary
on the generator except the replacement of parts.
Current Regulator
The current regulator consists in part of two coils
that go to make up an electro-magnet. When the
cores of these coils are sufficiently energized, the
armature is pulled downward against spring tension,
opening the contacts and the shunt field
current is diverted through a resistance to the
ground. This resistance greatly decreases the field
current, and the output current flowing through
