Well here's a related question that might seem laughable to some of you
guys who actually know stuff but asking anyway...

   When I go to identify the Ground wire in the wiring to the plugs for my
headlights...How do I determine that?   Can I do that with my test probe
light, the one with an alligator clip and a wire with a bulb and ice-pick
arrangement on the other end?  Or if I use my digital multimeter set at 20v
as a tester, I should get a 12. xx v reading (headlights on, of course) but
should that be a + reading from the power source and a - reading when I am
on the ground, or how?

  Or do I have to determine the wire from the diagram after I figure out
which diagram is correct for my M.Y. vanagon in my particular copy of the
Bently.

  see?   Laughable, but still un-known to a dunce like me..
