Is there a source for Electrical Schematics for the 2006-2008 K1200GT's?
Is it possibly included with what I understand is called the K44 RepRom?
No, the K1200 GT wiring diagram is packaged with other models in a DVD labled (in my edition) as SLP 2.1. It covers several languages and models from R1200's to k1200's. Mine is only through 07/2007, but later ones may cover 08 and or 09.
Get it through your dealer.
Has anyone know if you can get a wiring diagram for these bikes. The electrical system seems to be a major problem with these bikes.
My '06 has been problem free with the stock electrical so far, but it uses the higher-quality (i.e. "proven") switchgear than the '09's and it also looks better too, imho.
Other stuff, like Autoswitch, Autocom, and assorted audio-ground loops, have been things not associated to BMW. Many of those were dealer installed at purchase and they managed to screw a lot of it up - even quit handling Autocom shortly thereafter. I didn't want to be responsible for any additions under warranty since the diagrams were only available to them at the time (it's not on my DVD either).
Now if you are referring to the electrical issues on the 2009's....
