The TR2-3B gauge works the opposite of all the later gauges, grounding the
sender wire should make it read empty (or a bit below).

Note that the body of the gauge needs to have a good ground (again unlike
the later ones).  I believe the factory originally installed a ground wire
from under one of the thumb nuts over to the ground junction on the panel,
but it's missing from most cars.
