Thread: Booster Pump humming

    Booster Pump humming

    Polaris Booster Pump Motor B625 is humming away. I tried:

    Replacing the start capacitor ( same specs)
    Hitting the sides of the motor
    Spinning the shaft while the motor is humming. Shaft spins easily.
    I removed all the wires from the motor and then plugged them back in

    Which leads (wire colors) can I check with my meter to make sure that it is getting the proper voltage?

    Any other ideas?
