Good evening. Right here's my long term problem. Car battery had not been holding charge. left in garage alarm off and still drained. Got new Bosch battery so for the last two weeks long trips car been fine. Left in garage alarm off again battery flat. Starter pack on jumped it went for a 20 mile drive came in had me dinner and car dead as a dodo. Notice that charge indicator on battery remained black instead of green showing it should be charged. Assumed it was the alternator so today set about pricing one. Feck was I shocked!!.
Anyway tonight I put a meter on the car and find the alternator appears to be giving a charge but notice the car is losing half an amp when switched off.

I went down the fuse box pulling fuses with the meter on to see if there was any change. Got to a 30 amp fuse in engine bay marked "AM2" and low and behold here's where the drain is. Checked EPC there states it's fuse no 18 and if I'm right states fuse for starting system.
Not an electrician or anything but what there could be causing such a drain.
I thought it was maybe the laserline cat alarm. Is that wired into the starting system etc. Taking this fuse out with car running stalls complete car and puts all dash lights on. Also not had any battery bulb in car from purchase? Something hidden perhaps. Or maybe it is the alternator and I've had a bum steer.....

Any feedback from you wonderful boffins would be much appreciated. :)
