Alternator problem or not?

Help please:
I have a Mini One Cabriolet and last weekend it just decided to cut out on me mid reverse! No warning light, no nothing....I had been running around in the car happily for half an hour or so before it cut out.
I called the AA who diagnosed the fault to be the Alternator. New Alternator purchased and fitted but my mechanic is still having problems. Initially the car started no problem but the battery warning light remained on until he gave it some revs....it went off after 15 seconds or so. When stopping the car and starting it again, again the battery light remained on briefly! My car was taken for a good 14 mile run, the light was off but then when starting it up again later in the day it battery light was on and now STAYS ON! Power steering is lost (I'm told as there is not sufficient charge in the battery).
The garage who supplied me with the new Alternator advises it was tested before it was shipped. My mechanic advises the battery is holding its charge and so it must be an Alternator problem...and I'm stuck in the middle
Has anyone come across anything this before, or can anyone offer me some advise.
Your hoping Laura

What year is your Mini and is it the original BMW battery?
Battery needs to be properly tested under load not just for holding a charge. If in doubt replace it.
If it is over or around 5-7 years old it will be near or at the end of its life and due for replacement. Modern batteries fail suddenly as you described with little warning. The electric power steering pump on earlier Mini's puts a high demand on the battery particularly while parking and reversing at slow speed.

Check power steering pump for internal fault......you mentioned it is it not working and they can also affect alternator and therefore the battery charging system when they go faulty.

Cooper "S" R53 Power Steering Pump Failure
"A Mini Cooper "S" R53 was driven into the shop last week. The alternator light was on, and there was a horrible burnt smell and smoke coming from under the hood. Once the smoke cleared, (literally) we checked what was going on. My first thought was alternator seized up and the burning smell was the belt. The belt was moving freely, and the smoke had stopped. However the power steering had stopped working. Evidently what has happened the P/S pump had grounded internally causing the large positive power lead to the pump to begin melting down. Is the power steering pump the cause of the melt down or the result of the melt down? Once we removed the burnt power lead from the P/S pump the alternator light went off and the alternator was able to charge the system. Evidently the alternator was severely over loaded to a point where it was not able to keep up with the demand."
