terminals. See
that
the small carbon brush
on
the
inside
of
the moulding works freely
in
its holder and
that
the terminals are secure.
Examine the contact breaker. The contacts must be
free from grease or oil.
If
they are burned or blackened,
clean them with a very fine carborundum stone
or
with
very fine emery cloth (see Fig.
7).
Afterwards wipe away
any trace
of
dirt
or
metal dust with a petrol moistened
cloth.
Cleaning
of
the contacts
is
made easier
if
the
contact breaker lever carrying the moving contact is
removed. To do this remove the nut, washer, insula-
ting piece,
and
connections from the post to which

the end
of
the contact breaker spring is anchored.
Th1
lever can then be lifted off its pivot pin. After cleaning
check the contact breaker setting.
If
the contacts are badly burned, they should
be
renewed. Replacement contacts must only be fitted
i11
pairs. To remove the moving contact, follow the pro·
cedure outlined above.
To
remove the plate carrying
the fixed contact take out
the
two screws complete with
spring washers and fiat steel washers. The replacement
set
of
contacts can now
be
refitted by a reversal of
the above.
Check the adjustment
of
the contact breaker gap
as described in
"After the first 500 miles running".
