I drove to Glasgow last Sunday, parked the car, everything great. When I came back after a couple of hours, started the engine, there was a loud whine coming from the engine bay, in sync with the revs, and the red battery light in the dashboard on. Opened the bonnet, the sound was comming from the alternator. Thought it was a mechanical problem, but then disconnected the alternator plug (the plastic one with 4 pins), the whine disappeared and the dashboard lighe went off. Put it back, the whine and light are back, meaning it is an electrical issue, not a mechanical one. Has anybody experienced something similar? Many thanks in advance for your help!
