I have a Nissan Micra K12 1.2 automatic 3 door hatchback. When the car is at idle the battery light is off, as it should be, but when I put my foot down the light comes on. It then goes back off when I back off the throttle.

If I keep my foot right down it keeps flashing and comes up with a charging warning and tells me to contact a Nissan dealer. There is no loss of power or electrics. The person that owned it before me has had the problem for ages but hasn't effected the drive at all.
