I recently purchased a Bass Tracker Tournament fishing boat, 1989. The bow has a Minn Kota Edge 70lb thrust trolling motor. Also on the bow is an electrical panel for trimming the Mercury 150 motor. Next to that is a sensor dial and a larger dial that should be the sonar unit. As I'm new to this type of boat...I don't know how to check to see why the sonar unit does not work. It's a Humminbird. The trim switches next to it work just fine. The in- dash Hummingbird sonar unit on the drivers panel works as well as the Humminbird Fish Finder mounted on the counsel. Just the bow unit does not work. I'm sure it's a simple fix but this boat was purchased without a manual for anything.
Oh, and where are the fuses located.
