Thank you! As it turns out, it sounds like I chose the same location on body, and
decided to attack it with a dremel this morning after last night's failed attempt, just in
case it wasn't clean enough. Still no change... :-(

Ok, here I used the smaller + terminal, with the blue wire which I believe goes to the
alternator dash light. Is there a difference between this and the larger terminal? I
assume there must be, because engine off, I get 12V difference between them, yet
with engine on I get 12V between each one and ground. Does this make sense?

Well jeez, I want my money back then! ;-)

Seriously, thanks for relating your efforts, it certainly can't hurt to try it...
I've now checked nearly every electrical connector (all clean, except oil press and
temp sender connector), except the temp sensor on the front of the t-stat housing,
which is near impossible to reach from above. I hesitated to crawl beneath, as the
van was still dripping coolant from my less than stellar attempt at replacing the
coolant level sensor without spilling a drop. I confirmed the sensor is identical to the
one I just replaced last year on my Jetta, so I borrowed it and proceeded to test fit it
in the Vanagon tank... and promptly broke it. So in one fell swoop, I've managed to
put both vehicles out of commission. Great. So now I am waiting for JB Weld to
setup on the slightly less broken Vanagon sensor (it has small crack on each probe)
in the hopes it will last long enough to get another sensor, so I can repeat this whole
process tomorrow night. :-(
