My ground wire will no longer reach to the coolant reervoir since i repositioned the PC under the seat. I was thinking this screw (my thimb is pointing to it) might work for a ground if I sand the paint down below the head of the screw. My only concern is that this screw is in a bolt on part of the frame and paint probably insulates it from the rest of the frame. I mean, if paint is confining the ground to this one bolt on piece, it would be a pretty small chunk of frame. Would that matter?
