weakness is indicated, the motor and other components should be
checked individually. If the motor is disconnected at the motor
terminals, connect one test lead to the grounded motor housing and
the other lead to one of the motor leads.
DC motors -Disconnect the motor from the line. To test the brush
rigging, field coils and armature connect one test 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 test lead to each of them individually, leaving
the other connected to the grounded motor housing. The above also
applies to DC Generators.
CABLES
Disconnect the cable from the line. Also disconnect the opposite end to
avoid errors due to leakage from other equipment. Check each
conductor to ground and/or lead sheath by connecting one test lead to
a ground and /or lead sheath and the other test lead to each of the
conductors in turn. Check the insulation resistance between conductors
by connecting the test leads to conductors in pairs.
