NO-LOAD TEST - CONTINUED
tight, dirty, or worn bearings, bent armature shaft, or loose pole shoes, which would allow
armature to drag.
No operation and low current draw could mean an open field current, open armature coils, poor
contact between brushes and commutator, or high insulation between commutator bars.
Low no-load speed and low-current draw could mean poor connections inside motor, defective
leads, or dirty commutator.
High free-speed and high-current draw could mean shorted field coils.
Starting motor (1)
Disconnect all leads and test equipment.
and solenoid switch
Remove motor (1) from test stand.
