In this context, 350k is far from an open circuit.  The sender is fed 12v
through a one-megohm resistor, at least on the earlier arrangement -- and
the evidence to date indicates that they didn't change the LED panel for
the new sender.  The LED panel senses voltage and has an input impedance
that could easily be ten megohms.  In stock form it should light green if
it sees btw 0 and 3 volts, Yellow from 3 to 5, Red from 5 to 7, and no
lights above 7 volts.  Again, I'm speaking of the '84 version and we have
not yet established for certain that the later ones are identical.  Occam
thinks they are, though.
