If you didn't leave the key in the Park position to drain it, before you buy another battery, see if you can charge it up again, then test for some other current draw with your meter as follows: Disconnect the negative cable from the battery, hook up the meter in between the negative terminal and the ground cable and set it to measure amperage. There should be 0 current flowing if the bike is off and there are no shorts anywhere. If you get any kind of current reading you have a draw on the electrical system and have to start tracing all the wiring to find it. If you measure 0, then get yourself a new battery, charge it, and then see what happens.
(Just trying to eliminate some other problem and try and save you money too. This is all a process of elimination instead of just shotgun buying new stuff and hope that solves the problem.)
Good advice about shotgun buying. Already bought a replacement battery, though. I'll test as you have suggested to make sure there are no shorts, but even the light indicators on the tender pointed to a problem charging the old battery.
