You could check it by measuring one while applying
(and not) a load to another. I suspect GM would
would have put some current limiting between pin
and the 5V regulator. In which case the deflection
would be too small to measure if the regulator is
any good.
What does commonality matter, and is it nonviable
to pick up a 7805 to make your own +5V? How good
do you need it to be?
