I'm a Sparky by trade. I've noted appreciable Vd over
very short distances (1-2m) at 12v on my own setups, the main culprit being undersized cabling, and weak power supplies.
I run minimum 12-16awg multi-strand flexible tinned automotive cable for all my main 12Vdc cabling runs (I'd need to confirm what my current setup is using), and these are kept to a minimum length.
My 12Vdc source is kept on the mount tripod.
Runs out to pieces of equipment (camera, flats panel, focuser, dew hearers etc) are usually in 18awg.
