This may be really simple, but I want to make sure before I go to a garage.
Basically my battery light comes on when the engine is on and stays on until I go over 2k revs then it goes off, but as soon as I brake or go under 2k revs the light comes back on again.
Is this just that the battery needs charging? It started just after a 2hr drive up to buxton so I would have thought the alternator would have charged it? :S

Its a long shot but maybe the alternators weak and its not charging efficiantly below 2k rpm?

Seems to have sorted it out at the moment. But I had the aux belt changed in June, so shouldnt be slipping.
