REMARKS

NO-LOAD TEST - CONTINUED

NOTE

Low rpm reading and high ammeter reading could mean too much friction on armature shaft, also

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.
