Evening, hoping someone can shed some light on an odd charging problem my Trophy's sprung upon me. I had a new alternator fitted a couple of months back and all was well until a couple of weeks ago. The car runs fine but after about an hour's continuous running if you turn the car off the battery's dead (car wont even turn over). I've put a multimeter over the alternator which is kicking out 14V, but when I checked the battery it was only showing 11V going in. Seems like a wiring issue perhaps? Has anyone had a similar issue? Also, the alarm has started making 2 very loud beeps on locking and 1 loud beep on unlocking (same tone and noise level as the continuous beep you get if you've left the bonnet open and lock the car).

i think it may be possessed (or perhaps just French). Thoughts and advice gratefully received :)
