I have a 2002 searay sundeck 190. Problem is with the switch pad that controls depth finder running lights engine compartment vent blower and horn. All of these functions are controlled by this switch pad. The only thing that works is the horn. The other things will work sometimes but mostly don’t work. All fuses are good. I figured the problem was the switch pad so I replaced it. Everything worked after that until I put boat in the water. Now back to just horn.any ideas?thanks
