I've seen this with motors on speed controllers (jags I think), where a metal wharf will get in the speed controller and fry something (a FET I believe, but I can't tell you why) and permanently close the circuit that the speed controller controls. No control (ie stop) signal will change this. I'm sure one of the more experienced guys on here can speak to the exact happenings when a metal wharf gets in a speed controller.
