Thanks for the info guys!
Could be the alternator, but not sure how to check.
The battery has gone flat before, and I had it slow recharged (with the yellow charger?) for about 2 hours. It all looked sweet and the battery seemed charged. But 3 weeks after...its dead again. I guess the car's only a weekend car, but I dont think its normal for a battery to just wear out so quickly....
