You could see if there is a way to unclog the wires and check continuity (ohms) across the motor.
That gets easier if there is plug somewhere on the other end of the wire, so you do not need to desolder the motor.
Turntable motor voltage issue?
My 20yo (1999) Sony PS-LX250H motor is not turning on its own, but I can easily turn it by hand. On the motor's side, the label says it is a 9.12Vdc motor. When I measure the input on it, it gets only 8.3Vdc. Am I doing this right? (I'm a total noob when it comes to electrical stuff.) Would the voltage drop be the cause of why the motor is not turning? Please see attached images. Any ideas on what could be causing the problem? Thank you.
