New cluster did not fix the dead Gauge issues HELP

humm I could use my multimeter to test the Wall wart output to verify polarity and voltage output.
Sadly I do not have a garage, just a driveway.

Let me also ask, the Fuse for the dash, that is for all dash lights correct? So if the turn indicators work and the Hi Beam indcator works, then the fuse has to be good, right?
i gotta get the Dash lights working, the ones that illuminate the background.
And the Headlight switch with the Rheostat is new. Other silly question, does the Dome light dim with rheostat or is Dome light just either On or Off?
