BRUSHES AND SLIP RINGS
Brush Inspection
Remove the brush block cover and inspect the
brushes and brush holder for burns
or
other dam-
age. If the brushes
appear
to be in good condition,
use a piece
of
wire (marked
as
shown in Figure 8-9)
to check for excessive brush wear. Insert
the
wire
through the hole above each brush. Make sure the
wire is resting on the brush and not on part
of
the
spring. If the painted part
of
the wire is not visible,
the brush is excessively worn and must
be
re-
placed.
