The headlights DO NOT get power from the fuse panel. There are two sources of power to the light switch. The park/ tail / marker and dash lights come off the tail light fuse
But the HEADlights have a splice which comes directly off the BLACK ammeter wire up in the harness. This "main splice" IS NOT FUSED except for the main fuse link. This splice branches off and feeds
ignition switch incoming power
fuse panel hot buss
varies on year to year
and last feeds the light switch for headlights. The light switch has an INTERNAL breaker for protection.
First thing to do is access the dimmer switch. With the light switch in "head" "any two" of the dimmer switch terminals should be hot. If there is only one, you have bad dimmer. If you have two terminals hot, and no lights, inspect the lighting feeds out through the bulkhead / firewall connector, the harness and headlights If no power at the dimmer, time to access the light switch.
Remove the knob by ungrounding the battery, and pull the knob clear out to "head." Reach up around and find the release button, then pull the knob / shaft out of the switch. Now you can remove the switch nut and pull it down out of the panel.
Then inspect the switch connector, and hook the battery back up, to check incoming power etc
