You will best be able to test this with a multimeter. Poke the + probe through the insulation after the fusible links with - probe grounded. If you are certain the fusible link is good, get to the headlight switch. Test the red wire coming into the switch for 12v+. If you are certain the switch has 12v, turn it on and test the yellow coming out of the switch. If that checks out test the tan and light green coming out of the dimmer switch on low and high beam respectively. If those check out, move to the tan and light green wires at the lights. Post back your results.
