The

The distributor mounting provides
a

of
properly
setting
the
initial ignition timing. The

The
battery and generaLing system
must be kept in
good
operating
condition
in order to obtain
satisfactory
opera-
tion
of
the ignition system. All wiring connections in the
ignition circuit
should be
kept tight
and
free from dirt
and
corrosion. Keep the high tension wires free from
grease and
tight in the distributor
cap
and
coil.
GENERATING SYSTEM
The
generating
system consists
of
the
generator,
voltage
and current.
regulator,
ammeter and
necessary wiring.
The ammeter indicates whether
current
is being
supplied
to or removed from the
battery.
The
generator
has
sufficient
capacity to supply all regu-
larly used accessories and keep the battery fully
charged
providing the
system
is
in good condition.

The
generator output
is
controlled
by the
combined
cur-
renl and voltage regulator and cutOUt
relay.
The cutout
relay
points
close when
the
generator
voltage
is higher
than
the
battery voltage so that
current
can
Row
to
the
banery
and open when the generator voltage is lower
than the
battery voltage
to
prevent the battery from discharging
through the
generator.
The current
regulator protects
the generator by
preventing
the
generator output from exceeding
45
to 51 amperes.
The
voltage regulator protects
the battery
and
electrical
system
by
preventing
the
generator
vohage
from
exceeding
7.0 to 7.7 volts.
The
cutout
relay points
open at 0-4 amperes and
close
at 6.4
volts.
The connections
in the
entire generating circuit must
be
kept tight and free from
corrosion or anything that wiJJ
