My test light is very dim, when testing the fuse box AC spot, when the fuse is out. I do have the truck running and AC going full blast.

This sounds like it can be one of two things, first I would check the alternator output.

If it checks out I would wiggle the positive battery cable (truck running) to see if the voltage comes back if so the positive battery cable needs to be replaced.
Please let us know what you find.
