Hi all. I'm new to all this forum stuff, and don't know much about my 1995 850T5 auto estate either. I am being given the run around between the garage that fitted a new battery(3 Year warranty) 2 years ago who claim the battery is OK and the car isn't charging properly ie it must be the alternator at fault, and an independent Auto electrician who says there is nothing wrong with the alternator, it IS charging OK.
According to the little green light that is integral to the battery; when I switch on headlamps the charge gradually drops until the light shows as discharged. When headlamps are left off the battery recharges after a run and battery light shows as OK. The point is - is the battery really faulty? Is the alternator acting up, or is something else entirely to blame?

Any suggestions to help me decide what to do next would be most appreciated. BTW I'm a complete novice at car electrics.
