Dodgy Electrics HELP!!!!

[settert4]

Morning fluffers,
Should point out that this is a Vauxhall Astra H 1.9 CDTi im talking about.

Started off with the Alternator going, the usual - Battery light came on, then it was just a matter of time before i ran out of battery.
Then due to this my battery wouldnt hold charge, kept dieing everywhere but once bumped was fine (At this poin i had my New Alternator)
So i replaced the battery and all was fine and dandy for about a week.

Now on the way to work this morning i noticed it struggling to start like the battery was low again, (New battery and alternator)
and when i arrived at work the battery went dead - warning lights came on and CD player went off etc.

What could be causing this??

Check the leads on the alternator and battery get it running then put a meter across the battery terminals should be saying around 13.7 - 14.9
