Re: 2006 K1200LT High Beam and Windshield Motor Issues
I agree you are missing a wire somewhere. I don't know how much of a harness change you did but the most common mistakes are with the reverser controller lines. There are three large (10.0 mm) black with yellow stripe wires. Each has a different colored sleeve on it. The one with the red sleeve goes to the battery +, the one with the black sleeve goes to the starter tie point (see pic) behind the battery and the one with the brown sleeve goes to the ground tie point.
Another area is the starter relay output line, it is also black and often is installed as a ground by mistake, it goes to the starter tie point. If you did do this the starter relay is shunted straight to ground (this sounds like the issue). All grounds on BMW bikes are brown wires and in the harness there are two wires with eyelets that attach to the top of the transmission and frame right behind the starter motor (see pic). There should only be one Brown wire on the battery ( - ) terminal.
