Check for power at the Red/Yellow wire at the dimmer switch with the headlamp switch in the on position.
If power, check for power at either the green/black, or red/black wires, depending on how the switch is "switched" if no power to either wire... replace dimmer switch.
If no power to red/yellow wire, check the connection at the headlamp switch where the red/yellow wire comes out. if power you have a wiring fault between the headlamp switch and dimmer switch.
If no power replace the headlamp switch.
