I hit a dog while driving at night, the impact resulted into damaged left hand side fog light bulb burnt out, low beam went off on the right side, cracked washer bottle. The car was able to move for the 120km, thereafter it flashed "Battery/alternator," but it could start and run smoothly, until when a constant display of the high beam appeared on the cluster display, then it wont start. what could be the problem. Each time i open the door the cluster displays normally but with the high beam illuminated and the key will be sucked but it wont start.
