Right - so no volts getting to the fuse. Which means the fault is
in the feed to it.


I posted the Hayens schematic he

Can anyone decipher that and tell me what the relay should look like?

BTW, I'm puzzled by that schematic, because it doesn't show any
single- filament headlights. My low beam lights are separate,
single-filament bulbs.

Typical Haynes - trying to show every possible combination of all
variants in the same diagram. How I hate them. ;-)

Looks like there are only relays involved if you have daytime running
lights?

The car has no daytime running lights. There is a relay labeled "main"
being an 80A relay. Would that mean 'main beam'?

Where are you looking at? There is a relay labelled 'Main' in the fascia
relay box that feeds various 'ignition on' circuits; it will have nothing to
do with the lights.

There are either one or two under-bonnet relay boxes shown in the link I
posted. The smaller one of the two holds the headlight relays, but may not
be fitted to your vehicle.

If there is no relay for the low beam bulbs, this means that the full
current for both low-beam bulbs goes through a single headlight switch
contact, yes?

If your vehicle has only one under-bonnet relay box, then that is the case,
yes.

Whichever arrangement you have, if your fault is with the dip beam in one
headlight, the problem can only be at or after the fuse box, because
everything before that is a single circuit.
