On Saturday I got a new front tire (Pirelli Angel Scoot), and everything worked fine. That afternoon I swapped windshields from the stock to the Givi 5606 for winter riding. Again, everything was fine.
This morning I started it up as usual. When I rolled it out of the garage into the driveway, I noticed that the dashboard (LCD screen(s)) were blank. No image on them, and no backlight. The engine was idling, and I also noticed some resistance as I was rolling it out. I shut it off, then tried to restart. Nothing happened. No click, no starter noise, nothing. I moved all switches to the off position, and put it on the center stand. Turned the key to run and the on/off to on, and again, nothing happened when I tried to start it. So i backed it in to the garage and connected the battery tender (just in case), and told the wife that I was taking the car to work today.
I always park it with the handlebars in the lock position, with the key out. Nothing is plugged into the USB port. The temperature was in the low-60s overnight.
Any ideas as to what might have caused this?
