Try the fuses again.

Look at the fuses for discolorization, bluing of the brass ends. Discolorization is evidence of overheating due to a loose connection. The clips may not be holding the fuse tightly. This will cause fuse failure.

If the fuse is discolored, the clip will be heat damaged as well and the springiness of the clip is gone. A new fuse clip of disconnect box will solve the problem.
