2006 Triton Tr-21x. Dash is all push button. Strange occurrence this am. Master switch in back gets turned on right before launch as usual. I walk to do some other things and "entire" dash lights up. I didn't do anything. Hit power button....nothing...they stay on. Only way to get them to go out was to turn master off and back on. 10 seconds later same thing. This goes on several times, until they finally quit coming on by themselves. A little damp and drizzly this am, but don't think that had anything to do with it. What could cause this little gremlin?
