I can't intelligently speak about the 800 but on my 750 the rear lights in the factory turn signal housings were only for turn signals, not lit all the time as running lights. However, I switched mine out for LED units that made them not only turn signals, but also always-on running lights and brake lights, too.
Are you sure that a PO (previous owner) didn't swap the stock units for LED units that also turn them into running lights?
This past year my left rear setup developed a short at a spot that was chaffing into a metal thingy. This played all sorts of hell with the functionality of the lights. Once found and corrected, they worked fine. (Moral: look for wire chaffing.)
Now my right rear factory housing itself has crapped out so that the turn signal function is out even though the rest works. I'll be swapping that housing out sometime this winter.
Bottom line: Look for shorts. Determine if you have an LED conversion (if so then you may have to get all new units). Hopefully an 800 rider will pipe-in soon with their specific 800 knowledge for ya.
