tion
to
locate and
remedy
the
causes of
some
of
the
more
usual faults
encountered.
The
sources
of
trouble
are
by no means always
obvious, and in some cases a considerable
amount
of
deduction
from
the
symptoms
is needed before
the
cause is disclosed.
For
instance,
the
engine might not respond to
the
starter
switch:
a hasty inference would be
that
the
starter
motor
is at fault. However, as
the
motor
is
dependent
on
the
battery.
it may be
that
the
battery
is
exhausted.
This. in
turn,
may be due
to
the
dynamo failing
to
charge
the
battery.
and
the
final cause
of
the
trouble
may be, perhaps, a loose
connection
In
some
part
of
the
charging circuit.
If,
after
carrying
out
an examination,
the
cause
of
the
trouble
is
not
found,
the
equipment
should
be checked by
the
nearest
Lucas Service
Depot
or
Agent.
Much needless damage can be done
to
items
of
the
equipment
by
attempting
to
correct
faults
without
the

and
experience.
