It's been a long time since I connected this, but referring to my diagram at
http://www.n56ml.com/electrical/index.html , and knowing how I'd have
drawn it if it were a ground, I think it's power to an LED or bulb that
is already permanently grounded, and would be lit when the alternator is
not charging (whether or not the engine is turning....only if the
ignition is on and it's not charging. In your test, were all the other
pins connected, including number 5 to 12V (representing the ignition
switch)? This may be a factor. You may have more luck with this
question on the CorvAircraft list, as there a lot of other Corvair
engine users on that list.
