or
by a short
circuit
in
a
Íield wire. In either case, there
is
no
control,
and the
generator
is running wide
open.
To test
for this type trouble,
it must be
remembered
that
there are
two
basic
types of
Íield circuits, one
earthed at
the
regulator
and one
supplied
with
current
at the
regulator.
By removing the field
wire from the
regulator, the
generator
can be
isolated.
the
generator
still charges with
the Íield wire
removed, then the
earth
or
short
is in the
generaïor
itself.
AnotheÍ
generator
check can be made by
removing
the cover band,
lf
the inner surface
of
the band is
sootted
with
a
layer
of
solder,
this
indicates
that the
generator
has
been overloaded, and the solder from the commutator
slots has melted. This
would
lead
to an open circuit of
the armature coils.
Voltage losses due to
poor
connections, cause an
increase
of operating
voltage
because the
generator
tries to overcome the added resistance
of the ciÍcuit bv
forcing current through at a higher voltage.
When the
voltage increases,
the
regulator returns it
to normal
by
regulating
the Íield. Therefore, even though the
battery
is
in
a
low
state charge, the
generator
output
remains
low.
Commutator
servicing:
Examine
the
generator
commutator for
pitting
and
wear.
One
in
good
condition will be smooth
and
Íree
from burned segments. Clean
with a
rag
moistened
with
petrol.
lf necessarv refinish
as follows:
Clean and
polish
the surÍace
of
the
commutator, using
very fine
glasspaper.
Do
not
use emerycloth.
Clean
out
between the segments
on completion.
Visual
inspection
mav
determine the cause of armature
failure. Breaks in
the armature windings
cause burnt
commutator segments.
Short circuited windings are
discoloured
by
overheating,
with badly
burned com-
mutator segments.
The
armature:
Apart from cleaning the
commutator as
described
previouslv,
there
is little
which
can be done to the
armature
itself.
Never try to straighten
a
bent
shaft
and
do not machine
the armature
core. Armature
windings
are tested with specialized
equipment which is
not normally
available to the
car owner. The only
check
Íor a suspected faulty armature which
he can
carry out
is
10 substitute an armature which is
known to be service-
aDte.
Servicing
brushes:
Check for sticking of the brushes in
their holders
and
for
excessive brush
wear.
To free sticking
brushes, clean all carbon
deposits
away and
if
necessary, ease the
brushes by lightly
polishing
the sides with
a Íine cut file.
Make suÍe that the
brushes are replaced in their
original
positions.
When renewing
brushes they can
be bedded-in by
placing
a strip
of
Íine
grade
glasspaper
around the
commutator and rotating
the commutator
and
glasspaper
by
hand.

Servicing
brushes:
Check for
sticking
of
the
brushes
rn
their holders
and
for excessive brush wear.
The brushes should
be
replaced
if their length is less
than 8 mm

away
and
if necessary,
ease the brushes
by
lightly

Make sure that the
brushes are replaced in their
original
positions.
