shes got a j reg rt, been driving it for ages no serious problems. came round to pick me up on the way out friday nigth everything seemed fine, then half way back to hers i noticed some of the lights out behind the rev counter, then the needle on the rev counter went mad and suddenly flew up to 6000 revs and kept twitching all over the place, this all happened when she was sittign at some lights in neutral. got back to hers went to start it and the battery was completly flat. ive charged the battery and everythign seems ok at the mo. im just guessing that a lead came loose or something shorted and drained the battery somehow. anyone got any ideas.
