other lead to One of the motor leads. DC-Disconnect the motor from the line. To test the
brush rigging,field coils and armature 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.
