why has my battery started to drain. it is 100 percent the battery because i have put another one on and it still goes flat over night.my cental locking is de locked and when i press the key to close the doors it opens and closes 2 or 3 times is this the problem or somthing to do with it. i know its a matter of elimination but where would you start looking first. to eliminate the door factor which relays are to do with the central locking so i can remove them to try this first.any info would be much appreciated.
cheers
