It's a bit troublesome that none of your fuses show power...but the headlights aren't fused, so we'll ignore that for now. (I suspect an error in the test...dead fuses would show more symptoms than just no headlamps)
The headlamps are fed directly from the battery, through a fusible link, to the headlight switch, then through the dimmer switch and off to the bulbs. The headlight switch contains a 25a breaker for the headlights.
I'd start by checking for +12V at the red wire on the headlamp switch. Should be there since your fogs work...but check anyway.
If nothing there, the problem is between the battery and the switch. Likely the (red) fusible link @ the starter relay battery terminal.
If you have power there, check the red/white tracer wire coming off the switch. There should be +12V there with the headlight switch activated. If not the switch is bad.
If you have power at that point, move on to the dimmer switch.
Red/white is +12V in from the headlight switch.
Gray is low-beam out, Gray/white is high-beam out.
