The only other thing i can think it may be is the fancy alarm system ive instaaled. I bought it from the US and its one of those Color LCD Pager Alarms with Remote Start, but i cant see how it could effect the battery sooooo much??? I do understand that its 2 way, mening it comunicates with the pager unit, updating it as to the situation on the car, but how can it drain so much power. Any ideas anyone?
