does not
function,
first check
that the battery is in good
condition.
If there is 'no
fault
in the batotery, connect a ,Iead between the

measures,
replace it

REPlACING THE BRUSHES
When
replacing the brushes the
sta
rter motor is
re-
moved
and
dismantled
.
The
brushes are
soldered
loose
from
their attachments in the brush holder
and
field winding respectively.
The
new brushes
should
be soldered on quickly
and
with
sufficient
heat.
Solder
must not be
allowed
to
run
down into the
hrush leads as
this
will prevent the
movemeni
t of the
brushes in the brush holders and may reduce the
brush
spring
pressure. Brushes which have worn down
shorter than
14 mm (9/16")
should
be replaced with
new
ones.
