Hi all -
I'm still working through the problems with the lamps on my bike; it ended up not being the dc/dc transformer, so XTreme is sending me out about 5 different parts to swap out. I'm glad that they really stand by their warranty! (and, on the plus side, I'm getting free spare parts!)
During our conversation, John over at X-Treme threw the wiring diagram for the XB-600 to me, and now, I'm sharing it with you.
I hope this helps out some of my fellow volt-heads.
PS: One very curious thing in this diagram is in the lower-left, there is a connection that says "speed adjust holder". I wonder if there is anthing connected to mine...
