Exclamation Electrical Draw pls help

Okay so, I went to go for a ride two days ago and lo and behold my battery was dead, mind you the battery is only a month old. I hadn't had it on a tender as the bike has an alternator and i had ridden it about 6 days earlier, was going to ride to get the battery charged up. Anyway I went to Wal-Mart and bought a trickle charger for it and hooked up while i went to work, turns out that the battery was at 2.4 volts so the charger wasn't even recognizing the battery (fml). Turns out because it was that low, it voided the warranty. Point is there's no possible way a battery could naturally drain that low on its own, the only possible explanation is that there is an electrical draw in the system somewhere but I have no idea where to even start. Has anyone else experienced this or if not does anyone have any clues where to start looking?

First thing is to get the battery charged up. Make sure the tender was hooked up correctly and not discharging.

Next you need to hook up a test light or DVOM is series on the positive cable and the battery and see how big of a draw there is.

Start pulling fuses one at a time until you get to one that makes the draw go away. Then you will know what circuit to look at with help of a wiring diagram.
