Can you test the motor alone. A shorted motor winding would be

Hey Sam,

Thanks for the response.

I disconneted the motor and slapped a meter across it and it reads 0.1
ohm across the motor terminals. Have I found the smoking gun?

What's a more normal motor reading?


What voltage is the motor supposed to run on? DC or AC?


DC...or at least rectified AC. The AC line comes onto the board and
hits a bridge rectifier. The circuit board components and motor leads
are all downstream of that. There isn't an enormous amount of
capacitance on the board.
