If the end bracket
has
b«n remo\ed from the armature
in dismantling,
press the bearing end braclcet onto the

s ..
otch
on tbe lamps and
op.:rate
the starter control.
If
the lights go dim, but the
starter
is not heard to
operate, an
indication
is gi•en
that
current is
flowing
through
the starter
windings
but
that
the
starter
pinio
n
N.8
is meshed permanently with
the
geared ring on the
flywheel.
This
was prob<lbly caused by the starter being
operated
wh
ile the engine was
stiU
ru
nning.
l
n this
case
the
starter
must
be
remo'/td
from the engine for
cumination.
Should the l3mps retain their
full
brilliance
when
the
starter
switch
is oper3ted,
check tbat
the
switch
is
functioning. If the
switch
is
in
order. eJtamine
the
connections at
the
banery,
starter .,.;tcb,
and starter, and
also checlc the wiring between tbese units. Continued
failure o
f
the
starter
to
operate indicates an internal
fault, and the
starter must be removed
from
the engine
fo
r
eumination.
Sluggish
or
slow
action of the
starter
is
usually cau><:d
by
a
poor
connect
ion
in the wiring which produces
a
high resistance in the
startor
circuit. Check
as
described
above.
Damage
to
the start
er
drive is
indicated
if
the
starter
is
hc:ard to
operate but docs not crank the engine.

Remove
the

examine the
brushes
(8) (Fig. N.4) and the commu-
tator.
H
old back each

If
the
mo,·ement is sluggish remo,·c the
brush
from
its bolder and ease tbe
sides
by lightly pohshong
with a smooth file. Ah•ays replace brushes
in
their
original positions. If the brushes are
worn so
that they no
longer
bear
on
the
commutator,
or if the brush ncxible
lead has
become
exposed on
the
running
face,
they
must
be
renewed.
If the commutator
is
blackened or dirty. clean it
by
holding
a petrol·moostencd cloth against
it while
the
armalure
is
rotated.
Secure the body of the
starter in
a

te>t
b)
connecting
it ,.;th hc:avy-gaugc
cabi<S
to a b<lnery
of
the
correct
voltage. One
cable
must be connected to the
starter
terminal and the other
held
against the
startCT
body or end bracket.
Under
these light
load
conditions
the starter should
run at n very high speed
.
