By dimmer switch, do you mean the headlight switch that rotates and controls dash light intensity? Or the dimmer switch on the floor that controls the high beams?
The headlight switch in the dash would've been my guess, probably not if you replaced it. Second to that would be a main ground somewhere. I haven't gotten that far in my electrical system rebuild yet, but someone here probably has! All your fuses look OK to me.
