Battery light came on this morning and stayed on after ignition. No problems with the drive to work (18 miles), but I noticed that when I the engine was idling (a bit high at 1,000rpm), the light was bright. As I moved off and the engine revs got higher the light gets dimmer, I popped the gear into neutral and revved the engine, expecting the light to brighten, but it's the opposite, it goes dimmer.
So when I get to work, tunr off the engine and try to re-start - dead battery (as expected).
I'll pop a new one on to get me home, but I'm guessing the alternator has gone ???
Has anyone else had similar .... the battery light going dimmer the faster the engien revs ????
