Regarding the 2 fuel gauge tabs on the fuse panel. The top tab has no power. The bottom tab has power. Shouldn't the top tab also have power with the ignition switch on?

The wires going into the ignition switch all have power.
All fuses checked and have power on every one.

Is the no power on the top tab problem in the fuse panel connection inside?

I'm trying to figure out why my fuel gauge doesn't work (it did before switching the printed circuit cluster).

In the diagrams, I see that the fuel gauge wire is connected to the top tab.
