There is a detached black wire near the fuse under the hood of the huskee 808k. Where does that wire go? Thank you

Hi,
Generally a black wire is a ground. You did not state if it had an end. The 808K was a Tractor Supply unit(and Cub Cadet used it.) Might it fasten to one side of the solenoid screws?
Peace,
