bit of help needed.
A family friend is with a friend in a fiesta which has just decided to break down after stopping at a supermarket. The car is completely dead EXCEPT that the speedo dial goes right round to 140mph!! (thats a first!!)
Anyone know what might be the problem (yes - I know its something to do with the oval blue badge on it!!!)
My first guess is the battery has a short in it, or the alternator has burnt through.
RAC are on the way tho.
