Problem is now sorted or at least thats what I hope. Had my window replaced (the one I smashed in order to get the lad who had climbed in through the boot with the keys and susbidentley got locked in the car when someone shut the boot) and locked the door with the key fob, the alarm LED stayed on constant and then flashed in a normal manner. So by my reckoning when I parked up on Saturday night one of the doors wasn't fully shut thus causing what would seem to be super sensitive sensors inside the car to trigger, this wasn't heard by me 'cos I was in a basement of a club stood next to a 2000W speaker :-/ this caused the initial drain on the old battery. The drain on the new battery would prob be cos when I temporary covered the window with a bit of plywood there was a gap, agian this would effect the sensors and drain the battery and also show up on the LED that something wasn't quite right with the alarm. So fingers crossed that now all my windows are intact and the fact that I am the original village idiot all will be well with the car. But if it lets me down agian this Saturday with alf a dozen tidy lookin girls stood there waiting for a lift home then it may well be advertised in the Car/Parts for sale section first thing Monday morning
