Field Coil Test For Ground
NO TE:
Be sure to disconnect the shunt coil before
perform ing this test (when applicable).
Place one lead on the connector bar and the other on
the grounded brush (fig. 2 IS). If the lamp lights, the field
coils are grounded.
Field Coil Replacement
Field coils may be removed from the field frame using
a pole shoe screwdriver and a pole shoe spreader. The
spreader prevents distortion of the field frame. Careful
installation of field coils is necessary to prevent shorting or
grounding of the field coils as the pole shoe screws are
tightened in place. Form ed insulators are used to protect the
field leads from grounding to the frame and must be replaced
with assembly.

should never be used on electrical connections.
When inspection shows com m utator roughness, it
should be cleaned as follows:
