The rear of a power supply connects to six bus bars, three positive and three negative. A replaceable crown clip provides the point of contact at each of the six bus bars. If a power supply fails, all six clips might need to be replaced.
Follow these guidelines when replacing the crown clips.
Use short screws for a negative bus bar.
Use long screws and a spacer block for a positive bus bar.
Use the torque screwdriver that is included in the repair kit. Set the screwdriver to 10 in-lb.

12 long screws, 1.625 in. (41 mm)
