A finger to frame or often the drum plastic bearing points break off cocking the drum and allowing the drum to short to frame and thus fingers touching the drum to frame. Again, typical failure is the drum- and when it fails, it can wipe out the fingers if they take current and heat up- they lose their spring and it's total replacement time of both drum and fingers.
