    The circuit works by feeding power to each of the lamps through their respective fuses, and then control the ground circuits for them with the multi-function switch. The Red/Black wire is the ground circuit for the high beam and since they work that confirms the entire circuit through the multi-function switch and it's ground. The Yellow/Red controls the ground circuit for the low beam lamp operation. That circuit has to be open between the headlights and the multi-function switch ground connection. Normal voltage drop testing routines should lead directly to the failure, and basically either the switch has failed or the wire is broken between the splice for the low beams and the switch assembly.
