The Crap won't charge.

[Exerqtor]

Just changed my fuel pump, (witch by the way wasn't fried, alltho the fuel gauge sender is). AND when i was taking the car for at test run i saw that my alternator light was glowing slightly. Then 4min in to the test run i started getting all sorts of warnings from the MID. First battery fault, then i lost my ABS and ESP. Then my headlights went out and i started to understand what was going on, and tried to rush back "home" to my workshop. But I didn't come that far since the car suddenly died. I got the car towed back to the shop and hocked up the charger and let it charge over night and until 30min ago.

BUT, the car still won't charge. And i didn't get any indications that something was wrong with the charing system before it stopped due to loss of fuel last weekend. Is it possible the ECM goes in retard mode or something? Or this might bee a common fault? Realy starting to get sick of shait coming in nice big packages when something happens with this car.
