Dan,
"Feed Lead Negative" means the ground is positive (Not Tiger)
"Feed Lead Positive" means the ground lead is negative.
On the face of the instruments, either Smiths or Jaeger, there are usually very
tiny letters, sometimes near the part number, that might say "Positive Earth",
or "Negative Earth", except, of course, ammeters, oil pressure gauges and
speedometers. Sometimes they put it on the outside of the case in the words
you mention, as well. I've not seen one that didn't have the face labeled, but
I've not seen them all.
