I attached the entire wiring schematic below for the headlamp (see pics 1 and 2 below). Are you getting power to the fuses and the relay? If you jump pins 4 and 5 at the relay, do they work? If they don't, chances are the fusible link is bad. Check pin 5 for power. It should have it at all times. (see pic 3 below)
Here is a link you may find helpful:
Let me know what you find. If you are getting power through the relay and the two fuses are good, they should work.
Take care and God Bless,
