@fdharper, have you tested the fuse block with a voltage tester? With the key on the "On" position, one side of each fuse should be hot. The only exception to that I can think of is dash lights. On my 69 Barracuda, the headlight switch is rotated to vary the brightness of the dash lights. That power goes through another fuse between the headlight switch and the dash lights (like @Mattax said). But testing to see if one side of the fuse is hot is a start.
