Y copper spade with copper nuts and post, shake proof binding washers and a torque wrench. Magic goo, a little dab will do ya, and torque um up.
No torque wrench a good end wrench, will work.. Look up the torque spec for the stud size... Perfect connection..
Or you can just give it a good tug, with an end wrench, plyers, or whatever's handy.. LOL
