So now that the OP's [and evidently several other members] problem has been solved, can someone explain to me what exactly happened and why? Is that a problem that I could unwittingly simulate on my '14 Ultra? Does this mean that modern generation Harley's can no longer be jump started? Damn, I've got a lot to learn!

What fun would that be? At least if they take the seat off and put a wrench in their hands, they'll feel like they had to put effort into it and it wasn't just an easy fix.
