DRIVE MOTOR
To check the motor, first remove the motor harness from the centrifugal switch. Then, set the meter to
the R X 1 scale and check the start winding for continuity by testing between the black and yellow wires.
A resistance reading between four and seven ohms should be present.
CENTRIFUGAL SWITCH
To test the centrifugal switch, remove the pump and disconnect the motor harness block from the
centrifugal switch.
Remove the switch from the motor, and remove the internal motor wires from the centrifugal switch.
Set the meter to the R X 1 scale and test the switch in the “start” position by pushing up on the switch
actuator. Continuity should be present between the red and black terminals and between the orange
and blue terminals. No continuity should be present between orange and violet.
Test the switch in the “run” position by releasing the actuator. Between the orange and violet
terminal, continuity should be present. Between the red and black terminals no continuity should be
present.
