The main beam relay feeds onto a link between fuses 17 & 18 7.5 amp (L & R) then out from the fusebox direct to the light units connectors on pin 1 The main beam uses a separate earth pin 6 which is commoned up inside the light unit to also provide an earth for the leveling motor, the dipped and sidelight earth is on pin 7 they then join up in a splice and go to a ground point Front R/H side of engine bay.

You could do a continuity check from the light unit connector back to the fuse, if this is OK this would prove the wiring and the fault is in the fusebox or check if there is 12volts at one side of the fuse this would prove the fusebox and that the fault is in the wiring either way you would know where to start looking for the problem.

If you would like a copy of the Ford dealers wiring diagrams contact me on nige110162(at symbol)hotmail.co.uk
