TD Fuel Warning Lamp

["Frank R. Krajewski" <frankk@businesson.com>]

Is there a test to determine if the sending unit on my 1953 TD is bad.
The green warning light stays on regardless of how much fuel is in the
tank. I have dutifully traced the wires and they are correct. The only
variable now is the sending unit itself.  I know with later model LBCs
with gauges it is possible to ground the gauge and see if the needle
goes to full but how does one conduct such a test on the TD and that
damn warning lite?
