I have a 1981 25hp evinrude I just bought and am looking it over and saw a loose wire. Where does the wire (shown in picture) attach to and what is it for? The motor seems to run fine without it....
Some solenoids have 2 small studs for wires to fasten to. One goes to the positive wire on the starter and the other
should connect to the wire that you have that is not attached to anything.
