on the motor. Using a multimeter set to 200 Ω (ohms), place the red (+) probe on the A1 terminal and
black (–) probe on the A2 terminal. The multimeter should indicate continuity. If the reading is incorrect,
a possible open or poor contact in a brush assembly and/or open armature windings may be the cause.
