I've decided to put my Garmin fishfinder 80 sounder on my bow mount Minn-Kota. I'm running a Hummingbird 777 on the stern as my main sounder.
The Garmin has been boxed up for 2 years and was the main sounder used on the boat.
The problem I'm having is when I turn the sounder on, the screen lights up for about for about 1 second (if that), and then it dissapears giving me a blank screen.
There's plenty of power, fuse is ok, connections look ok as well.
Could there be a corrosion problem inside the sounder maybe causing this problem?? There's no visible sign of any corrosion on outside of sounder.
Any ideas guys??
Thanks, Jeff.
