Sorry if this is the wrong forum guys but wasn't really sure which one to use.

So i have an EF gli falcon and lately the battery has been going flat pretty much over nigh so i checked the battery and found it has a current draw, i took out each fuse, one at a time and checked the draw and when i came to the fuse labeled CRT LP the draw dropped right down. I'm pretty sure i read that this fuse has something to do with the interior light, radio, alarm...etc and i was just wondering if anyone knows how i'd go about troubleshooting this problem???

Thanks for any help,
Luke.
