what is this dial on the dashboard of my 1987 357V ranger bass boat
I bought a 1987 Ranger bass boat. On the dashboad is a electrical unit that says oscale select. It also says: sensitivity and pull for suppression. What is this device and would it have anything to do with my lights not working nor is my aerator working.
why i bought the boat is a long story but i bought it in the winter so i couldn't put it in the water for testing and am a dufus when it comes to boat maintenance.
