998 1991 mini auto.
Just started to get this issue while driving my battery light come on and stays on. Then some time goes off.
I fitted a volt meter just to see whats happening.
During motorway the light is off and volts read 13.7
When stationary at lights it reads 12.0
When i'm driving and the light stays on the it reads 11.5v
So with this in mind likely dead battery or alternator?
