I did not jump it from a running car, so no worries about that. It tried to start, it just seemed to not get quite there with the battery connected to the car.
Battery tender for a while, got to 80% charged, started fine and I ran it for about 20 minutes to recover the start charge, seemed to idle fine, and didn't even need the clock reset etc.
It was indeed the parking light. It's a bit on the easy side to accidentally wind up in that position, but in some ways it was a good thing it happened in my own garage instead of in front a motel 200 miles from here.
Odd note: AMA roadside assistance will NOT jump a motorcycle, it will fix flats or tow you to a garage, but won't jump a dead battery. Just something to be aware of. How do I know? Yep, you guessed it... :thumbdown:
Only drag is by the time I dared try and start it it was too late to get the inspection done, so I guess I'm waiting around until next weekend for that little bit of fun.
