I agree with Paralyzed, it's probably a bad connection where you repaired the lead. What motor are you running ? Also, make absolutely sure the mounting screws aren't hitting the windings in the motor if it's a feigao type inrunner. That will make them cog and get very hot very quick. It can also toast the ESC if you run it that way. I had one that ran fine for a while, then started with the cogging, and the motor screws were barely hitting the windings.
