No Front Sidelight

The driver's front sidelight on my '88 110 started going out intermittently. To sort it out when that happened, I took off the lens, and tightened the grounding screw. Now, it won't come on at all.

I changed the bulb and fuse, and checked the wiring. There seems to be no power going to the positive.

Any thoughts? Perhaps I've replaced the wrong fuse? Any one have a diagram of the fuse box and what fuse belongs to it?

Thanks in advance.

Fuse listing attached. More likely to be a broken wire methinks...

Thank you for the image.

I hooked up a multimeter to it. The o/s is showing 10v, but the d/s shows 2v. I believe it's the red wire with orange stripe that the sidelights plug into, correct? The rear light seems to have no issues. Also, I checked that red/ orange wire and it doesn't seem to be cut anywhere.

What number on the fusebox does this wire feed to? Do I need to take apart the dash to get to it?

On a side note, I really dislike Lucas Industries.
