Sorry for being so short on patiance, I was just attempting to get in inspection of the parts that "move" out there.
While that is being done, electrical analysis can be taken on a bit easier also, at the important connections inside.
Since the bike came out, I have to say I've only seen reports of failure about 10 times, a couple of those were related to actual motor/drive malfunction, more were related to cleaning and lube of the mechanism, and only 2 or 3 were directly electric issues.
The disassembly and inspection thing seems the most fruitful to me, as once you are assured the mechanical drive is in fact not jambed, its on to electrics.
I find that many problems that pop up like this, are the result of someone twiddling with your bike when its parked, and you can't see it, people tend to push and pull and twist stuff, like a shield that's left up, and you never know that someone messed with it till it stops working...
Kinda like people twisting the stove knob on your bike when its unattended, and messing up the knob.
Best of luck sorting it out, hopefully its something simple, that assembly is a high cost item.
