A bit puzzled. My K1200LT (2000) was garaged for December/January. I had the battery on trickle charge. Two weeks ago I decided to take her out for a run. Disconnected trickle charge, turned on ignition, all dash lights on ready to go. Touched the starter button and there was a click, and everything died! No lights on dash.
Assumed battery had failed and left it (no trickle charge connected) while I was away for a week.
Today, armed with booster starter, got ready to tackle the problem. But when I turned on the ignition - all lights on dash came on. Tried starter, and she started no problem!! :confused:
So I am wondering is there some sort of cutout which may have activated, and then re-set itself?
All is well now - but I am curious as to what happened. Just in case it happens again!! :)

How old is that battery? Even on a charger battery's have a finite life span the LT is very sensitive to the amperage output and one failed cell will be enough to kill the its ability to start.

OK The reason all the lights went out was either a loose battery connection or the starter relay stuck on. There is a load shed relay that gets its ground through the starter and it releases (cuts off all the lights and loads) anytime the starter is engaged. There is also a small 5mm allen at the rear of the starter that provides the gound to the starter since it is double ended and has sealing o-rings on each end. If that screw is loose your light will cut out and the starter will not turn.

I am inclinded to say a loose battery connection or that 5mm allen is the cause of your issue.

Not at all, I would look at posting the question here first as being the most efficient way to go about troubleshooting!

Ride happy.
