Once you've found the fault it's really worth 1. changing the fuse holder to std blade type fuses, and 2. re-wire from the light switch/stalk to 2no new relays, one for each headlight - this ensure low current switching and will save your light switch contacts from burning out.
Both upgrades are very easy to complete.

Should be fairly easy to trace. Does it vary when running or not? Ie is the alternator working? What is the battery voltage?
Just follow the wires from the battery and alternator and see where the voltage drop is occurring. Might be worth checking and replacing the main Earth strap to the engine/gearbox too.
Btw if you have low voltage to the fuse box, it’s amazing anything is working?
Have you cleaned all the brass fuse holders up so they shine , as well as the fuses

what reading do you have at the lights?

Check accross each side of the fuse. They don’t always pass the power through.
Does the high beam flash?
Does the fog light work?
Asking as they are linked in a circuit with a relay,by fuse box.
You couldn't make it up, maybe your neighbour sneaked in and done it for a laugh!
