I got my Ranger new in 93, and at my age it looks like it will be my last lol, need some help with my Lowrance in dash flasher, I have a LED graft on the console and one on the front, I have not used the flasher in years, the LED on the console went down and I went to the flasher, the big knob next the dash turns it on and the small knob on top of the big one adjusts the power of the signal, wow what a mouth full!! the small knob will pull up! I don't know what it does when it is pulled up. if anyone can figure out what I'm talking about, please let me know

Thanks in advance

Gary
