At 11:29 AM 9/15/2004, you wrote: I've always lumped failures into HDA or Logic board. But I've never seen a short as you describe. Considering the thin enamel insulation on the wires, and the stress of winding the coils, I'm surprised it's as rare as it is. c'est la vie. Ed

How many wires does this motoe have in total? If quite a few (6 or more), then I would suspect a motor with electronic commutation on one of the drive PCBs, and it's quite common for the windings of those motors to have very low DC resistances (< 1 ohm). If there are only 2 wires, presumably power connections, I would still suspect an electronically commutated motor (you need to keep the speed pretty constant after all). It's possible there's some circuitry inside the motor, and perhaps a trnasistor has gone short-circuit or something. Can you get inside the motor at all without opening the HDA? (I know it's possible to remove the winding assembly from the motor on a Micropolis 1200 in the field, but it does need special tools...) -tony
