We had a bunch of rain last week here in Texas and a little green light came up on my multifunction display. Went to owners manual and there is nothing about this little green light in the far lower right hand corner of the display. A buddy indicated it might be water in the dash?.. The next day a bunch or RRRRRR came across the screen when I tried to start it. Now nothing. Will not turn over at all. Was running great battery 100% bran new all hooked up correctly. Help??? Please
