Has anyone got a schematic for this bike (K1100LT) and any test points to hit or a link to a flow chart

On the Home page you'll find the Technical Directory and in the Technical Directory you'll find a schematic for your Brick. Look around; you'll find many useful resources. Like this. Also, linked below. It discusses how the Motronic engine management system works in your Brick and might lead you to the source of the fault.

All the grounds are good the bike has been put back together with attention to these points.

The side stand switch is bypassed.

Im aiming to look at the key switch next however this just stopped while it was cranking over its like its deceased it just stopped cranking and all the dash lights went out.

So, did you check the ground connections and the starter brushes?

The ground connection from battery to transmission would be the first suspect in Gryphon's list.
 

The bike has been stood for a bit and started with the help of jumping it from my van. I ran it for about half an hour no problem ( jump leads disconnected ). Came to it the next day it would turn over but failed to start although it tried. Eventually I flattened that battery which is about 2 years old. So I charged it overnight and in the morning it showed as being  faulty which was a bit wierd. I then tried to jump the bike again from the Van and all that happened was everything went dead when I pressed the start button the lights on the panel just went out like its completely dead. Disconnecting the jump leads and trying later exactly the same. Taking the battery off and jumping directly from the van same. With the van running the voltage is showing 14V at the bike the jump leads are heavy duty. Essentially pressing the start button, assuming Ive got some lights on the panel, just kills everything.

Any Ideas on this would be great as I am at a loss here with what to look at.
