Thinks s/he gets paid by the post
To get a steady voltage test (assuming it has an easily accessible old fashioned electromechanical flasher), remove the flasher unit, and rig a jumper.

Tracing those wires (signal harness) brought me to the steering column and clockspring area, Grounds are very clean and no corrosion seen in any of a half dozen connectors. Good idea, though. Battery voltage is 12. - 12.6 volts everywhere I checked it. That includes at light housings in the fenders.
The truck has 46,000 garage-kept miles on it and no corrosion noted anywhere.

A ground can NOT be eyeballed and determined to be good it MUST be measured.
A bad ground will absolutely cause a voltage drop.
I agree. I didn't conduct a voltage drop test as I had no wiring diagram and 50 untested wires and plugs are in that area, including the clockspring.
I do believe my issue with measuring the 10.7 volts with a digital voltmeter at the mirror wire when cycling the blinker has to do with what EDR50 stated earlier and I suspected. So tomorrow I will conduct a "live" test with a LED and see how it performs connected to the output of the signal wire at the mirror housing location.
Thanks, 88 year old guy had it and I bought it out of the estate from his nephew. Even the leather seats are mint. Has all new brakes and tires. Came with the fiberglass bed cover and inside the bed it has a bed liner.
Well, it lasted a lifetime.That was a belt-and-suspenders kind of guy!
How about an update? I'm curious as to what you found.
