When I got in my car yesterday morning, the battery was almost flat (it had been fine up until then), it didn't have enough power to open the central locking let alone start the car. As far as I know, nothing was left turned on overnight, and the battery has been fine recently, and is only about a year old.
I recharged the battery for a couple of hours, and it started almost immediately. So I took the car for a drive to recharge the battery fully, and it all seemed fine. I stopped and restarted, and went out in the evening, and back again, no problems except that the radio wouldn't turn on, and when I turned the lights on in the evening, the dashboard illuminations dimmed considerably - that is more than usual.
This morning the battery is totally flat (not even the clock is going now!)
I assume that I have an electrical fault somewhere. The question that I have is - are there any simple faults that I can check for myself, or is this one that should go to a garage?
The car is a 1990 Ford Escort 1.8 Diesel.
TIA.
David.
