Well, I got it started w/ a jump and let it idle for a half hour. Then drove it around the block a few times, back to the house and shut it off. This morning it's dead again. No lights, nothing. So, it's back to the shop tomorrow morning for another check, probably a(nother) new battery... frustrating. But since the alternator checked fine the last time, it's either gotta be a bad battery or something that's not turning off and draining it.
Maybe the factory VehiCross "keeps turning heads after all these years device" is not turning off...
