CABLES.
Before
making
any
alterations
to
the
wiring
or
removing
the
switch
from
the
headlamp,
disconnect the
negative
lead
at the battery
to
avoid
the danger of short circuits.
The lead, about I
foot
long,
from
the
negative battery terminal, is connected to the
lead
from
the
switch
by
means
of
a
brass
connector.
The connector
is
insulated
by
a rubber
sleeve,
which
must
be
pushed
back
to
allow
the connector to
be
unscrewed.
Do
not
allow
the
brass
connector
to
touch
any
metal
part
of
the
engine
as
this
will short
circuit the battery.
When
connecting
up
again,
pull the rubber
sleeve
over
the connector.

The
panel
can
be
removed
when
the three
fixing
screws
are
withdrawn.
The
ends
of
all
the
cables
are
identified
by
means
of
coloured
sleevings.

HORN.
Electric horns are adjusted to
give
their best
performance
before
leaving
the
works
and
will
35
give
a
long
period of
service
without
any
attention.
If the horn
becomes
uncertain in action, or
does
not vibrate, it
has
not
necessarily
broken
down.
The trouble
may
be
due to a discharged
battery or a
loose
connection, or short circuit
in the
wiring
of the horn.
The
performance
of
the horn
may
be upset
hr.
the
fixing
bolt
working
loose,
or by the
Vibration
of
some
part adjacent to the horn.
To
check
this,
remove
the horn from its
mounting,
hold
it firmly in the hand
by
its
bracket,
and
press the push.
If the note
is
still
unsatisfactory,
the horn
may
require adjustment
and
should
be
taken
to
a
Lucas
Service
Station.
