Battery Dies - Even when Parked

Battery Dies - Even when Parked
Sportsman 400 4x4, model year 2001.
Just put a new battery in a month ago. Haven't run it for a couple weeks, went out to start it and got a very weak little turn, and I mean, VERY weak. Could barely hear the turn....
No lights working, etc. got her started by the pull rope and drove her around. Noticed even with it running, the lights were very very dim. Got her home and same thing, no lights, and unable to crank.
Here (to me) is where it gets strange. Pull the battery to put it on the charger, start her up with the pull rope again, and lights are nice and bright....what the heck is up with that?
Why is my battery being killed even when parked for a week, with the key out? And why would the lights not work with the the battery in while running, but take the battery out and the lights worked fine??
I think I have a short somewhere, but where to start looking.....

Battery tender is a good investment for machines that aren't ridden often. Check connections first for any corrosion or loose connections.Just because a battery is new doesn't mean that it can't be faulty. I've had bad ones straight out of the box that wouldn't hold a good charge. While running though, check that the charging system is ok,should be charging 14+ volts back to the battery. If the charging system is ok,have the battery load tested to tell if it has a dead cell. If the battery happens to test good,then you could have a parasitic draw that you'd have to track down.

Ok, so charge battery, left on my workbench, it kept the voltage fine for a week. So my impression is that it can hold a charge.
However, put it in the ATV, and two days later, it's down to 10.5v. Running the unit, I put the voltage meter on the battery, and it stays at 10.5. Seems like I am getting no charging from the unit. And I have some sort of "always on" that is slowly drawing the battery down.
Where should I start to look to see why I am getting no charging from the ATV?
