The
battery must be
well
secured in its box so
that
it
cannot
move.
The cable terminals should be well coated
with lanolin
or
pure
vaseline (not
grease),
before putting
the battery
into
service.
The top of the battery
should always
be kept
clean,
and as
far
as
possible,
dry; attention
should be
given immediately to the
least sign
of
corrosion occurring on
the terminals.
Keep the terminals and
connectors
well covered
with
lanolin or
pure
vaseline,
all
contact surfaces clean and firmly screwed
op, but do
not
use abrasives for
cleaning.
To
remove corrosion,
use a
solution
of
ammonium
carbonate,
applying with a
rag.
Do
not inspect
the battery with the
aid of
a naked
light, and on
no account disconnect
anv of
the
batterv terminals
or connections
when a charge
or dischar["
"urr.nt
is
passing.
The battery
must
never
be allowed to
remain
in
a discharged
condition. A battery not in
service should
be kept
in condition by
fully
charging
it and
then
giving
it
a
freshening
charge at
least once
every two months.
It
should
be given a thorough
charge
before being
put back into
service.
Care should be taken
to avoid an
inadvertent
discharge
of the
battery.
Such a discharge
may
occur
if
there
is
an earth
in the
wiring
system,
instruments
or
fittings,
or
if
the
ignition
switch
be left on
in
error, and the engine
happens
to come to
rest
with the
low-tension
contacts
in
engagement.
Provision is
made
for
the latter
contingency
by
the
red
warning
lamp,
which rvill
remain
illuminated
until the
ignition
switch is
turned off.
It should be
made
a practice,
when leaving
the
car,
always to
observe
that
the warning
lamp
is not illuminated,
and no switches
are
left on, and
that no
discharge
is
shown
on
the ammeter.

The
battery
ignition
contact breaker and
distributor
are shown
in
Fig.43, an internal
view
of
the contact
breaker
being
given
in
Fig.

A
condenser (4,
Fig.
aB)
is connected
across
the
contact
points.
In setting the points,
the
gap
opening
should
be .or9"
(.+8g
m/m.)
to
.o2r'(.SSS
m/m.), adjustment
being effected
byloosening
the
locking
screws
(3
and 4,
Fig.
44) and turning
the
adjusting
screws
(5
and 6)
to
obtain the
correct gaps,
measured
with
a
feeler
gauge.
Make
sure
that the locking
screws
are
correctly tightened
aftef
adjustment.
The
screws
(7
and
8)
must
not
be disturbed,
as this
would
upset
the
synchronism
of
the two
contact
breaker
arrns.
Every

miles, as
directed
on

at
the

apply
one
or two
drops
of

Also remove
the

and
apply
a
few
drops
of
