I rode about 100 miles yesterday, the longest ride since getting the Chieftain ('14) on New Year's Eve. I was almost home when the dash panel display started flickering on and off, then went entirely blank. No display at all. Then a brief glimpse of info followed by more blankness and occasional flickering. Shade or direct sunlight made no difference. After about 20 minutes of this, the display seemed to return to normal function. Any thoughts? I can't have this happening on a real trip.
