One day you can go out to it and it will start first time and trundle around all day long with no problem, the next day it won't start, no dash lights, nothing at all, however, it will fire up as soon as you put jump leads on it.
First thought was the battery, this has been changed, and then the alternator but it's happened again, the car is only 2 years old and has been back to the dealers who, surprise, surprise can't find anything wrong.
any ideas appreciated
