connect  one megohmmeter lead to the grounded motor housing and
the other lead to the brush on the commutator. If the resistance
measurement indicates a weakness,  raise the brushes off the
commutator and separately test the armature, field coils and brush
rigging by connecting one megohmmeter lead to each of them
individually, leaving the other connected to the grounded motor
housing. The above also applies to DC Generators.
