CHARGING BATTERIES
Fast Ch a rg ing
Tn'elve-volt
fast
chargers only should
be used
for charging 12-volt batteries .
Adjust charging rate as follows:
20 to 25 amperes maximum for 40 to 55
A,H, batteries
25 to 30 amperes maximum for 60 to 70
A.H. batteries
Battery temperature should not exceed 125
degrees
F , du
r ing charge.
If
the charger is not
equipped with a thermostatic cut-off, and the
batlery has not received sufficient char ging,
turn charger off until battery has cooled to 100
degrees
F,
before sta rting high rate charge for
continued charging,
Slow
Ch arging-
The slow chargers commonly used in sel'vice
stations are suitable for charging both G and
12-volt batter ies on the same circuit. Each 12-
volt unit must be conside red as equal to two 6-
volt batteries, and the charging rate adjusted to
suit the smallest 12-volt battery on the line.
Safe slow charging rates are determined by
allowing one
(1)
ampere per positive plate per
cell, l2-volt units.
40 to 55 A.H. batteries - Slow Charge-
4 amperes
60 to 70 A.H. batteries - Slow Charge-
6 amperes

several but-

As the batteries approach full charge each
cell will
be~in
to g-as or bubble freely. The
pat-
tery temperature should not exceed 125 de-
grees F. during charge; if this temperature is
reached, the battery should be cooled by reduc-
ing the charge rate or removed from the circuit.
The battery is fully charged when three sue·
cessive hourly hyd r ometer readings show no
rise in specific gravity.

Stock batteries should be boosted when specific
gravity reaches 1.225 specifi c gravity corrected
to 80 degrees F. or open-circuit voltage drops
to 2.05 volts per cell co rrected, to 80 degrees
F.
To HRsure trouble free operation on a new
battery installation. the battery
should be fully
charged at the time
it
is in.c;talled.

STARTER MOTOR
DESCRIPTION
The starter motor is a 12-volt four pole machine
Figure 3, Three of the field coils are connected
in series. Series connected motors
have a char-
acteristic of a high starting torque coupled with
a rapid acceleration. To stabilize the speed of
t.he armature when the load is reduced , the
fourth field coil is connected in parallel or
shunt . Shunt motors have a characteristic of
maintaining a constant speed.
This method of co nnecting the field coils of
the starter motor protects it against a too high
speed, in case the starter circuit is closed with-
out the starter pinion being engaged,
The brush holders are riveted to the fram e,
It
is necessary to remove the bearing and plate to
install new bru:;he~ and spri ngs.
The starter drive is the overrunning clutch
type and is shifted into mesh with the engine fiy
wheel by a solenoid,
The starter solenoid is moun led on the start-
er. The starter relay is sepa rate from the sole-
noid and is mounted on the left fender splash
shield in the engine compartment .
A neutral safety switch is provided for cars
cquipped with PowerFlitc Transmissions.
