The armature will vibrate back and forth on the same coil and eventually burn it out. Nope, no loud POP. It just didn't work. It used to run fine on batteries, then it suddently stopped.

Then, when I tried to use the power supply, the same happened... which means nothing. No POP, no weird scents, nothing. Nothing.
