Thank you Dennis, I use a Klein MM700 meter for all electrical (and
temperature or simple Hz!) checks. The idea of going through every light
circuit wire looking at resistance is daunting, but you're right. I
replaced several corroded or loose ground and fuse wire connectors, though
the under dash headlight and turnsignal/parking lamp connectors seemed fine.
I'll test the corner lamp sockets and pigtails to source any problems at
that end. Cunegonde sat for several years and might have external
electrical damage.
The headlights have local bodywork grounds to bare metal with dielectric
grease. There is continuity from those grounds to their bulb receptacles on
each side of the van. So the problem is somewhere in the switched wiring. I
really am stumped, but trying to avoid constructing and running new wires
from the driver lamp to fuse, and fuse to back of switch.
I need everything working and similar to stock, so I add my lighting
high-power relays and SA inner lights. You may recall I put the word out
for circuit diagrams and component lists to make the inner lights turn off
both simultaneously or separately from the outers. But I'm not modding
anything until I have stock functions.

I’ll ask for forgiveness in advance for sounding obnoxious. Besides
changing parts did you consider using a meter? Each headlight high and low
bam does have its own fuse, yes 4 fuses for the lights. They are after the
switches in the headlight circuit. The turn signal sounds like a bad
ground, probably at the socket itself. The 4 way flasher is not an
independent circuit. The flasher will not flash unless it sees enough
current being drawn for two bulbs. High resistance in the working or a bad
bulb will prevent the flasher from working. This acts as an indicator of a
turn signal being out. The 4 ways connect 4 lamps so if one or two were out
it will still flash. Headlight grounds are also a common problem. There are
grounding clusters above the fuse box. It is common for the quick slide
connecters to both corrode and also break just from heat and age. As the
headlights are higher current items new ground connections near the
headlamps are a good idea.

Subject: Dang driver lowbeam and front driver turnsignal
My driver lowbeam won't work at all.
What didn't help:
Swapped bulbs.
Replaced turnsignal ring & stalk.
Replaced dash headlight switch.
Traced wires and pulled apart the fuse block and driver's side wiring stars
connectors. (Should I try the passenger side one?)
In addition, the driver front turnsignal stays on and won't flash whether
just parking lamps, or either headlight combination is on.
BUT the driver front flasher works in emergency 4-way flasher mode
regardless of parking light/headlight configuration.
I know the 4-way flasher is its own circuit, so where in the
parking/headlight circuits are likely culprits?
Other than that, Cunegonde finally home and ready for visual restoration.
It's been a long several years since the engine debacle.
