Here's one from my Guard unit. So this tank is going downrange during Tank Table VII or VIII. The driver suddenly heard some odd thumps. Then he saw the rest of the crew out in front of the tank, shouting at him to get out. He looked back into the turret, and saw electricity arcing everywhere. He didn't bother investigating further, and abandoned tank. The crew ran some distance away, and stood around congratulating themselves on their miraculous escape from certain death. Then they gradually became aware of a kind of "chunka-chunka" sound. They turned around and saw their tank happily idling its way downrange. The driver was in such a hurry to get out that he didn't even take it out of gear. An NCO (possibly the 1ST SGT, but I'm not sure) had to jump on board from a jeep (and remember, electrical arcing, live rounds) to shut it off.
