Same happened to my son's 09. Water got in and shorted it out, killing the display. Take it off, take it apart and dry it out. If it still doesn't work, it's toast.[/QUOTE
Thanks for the reply, the next day I went out to check it and they worked again. Must be what u said and got some moisture in there. I rode it yesterday about 20 miles too and no issues. Hopefully they are all good.
