Many thanks to those of you who steered me in the right direction for a
replacement unit from Delta Six (Euro American).  However, based on some
excellent information I got from David Beierl <dbeierl@ibm.net>, I started
poking around a bit with my multi meter, and now I suspect that my LED panel
may be the problem.  I want to find out for sure before I lighten my wallet
for either of these components.  (Always better to be a good diagnostician
than a "parts-swapper" eh?)

My problem is that the test procedure outlined in the Bentley (97.30) seems
to cover a different unit than I have.  It says to "-connect other jumper
wire to white, yellow, and green wire of sender unit one after another"...
Well, my sender only has two wires - green and black.  Do the older style
units use 4 wires?  Anyone know the test procedure for the two-wire sender?
Or am I just reading this incorrectly?

The fact that I get three distinct impedance readings from the sender (but
only "clicks" from the top and bottom most positions) leads me to believe
that I should also be getting three LED readings, right?

Thanks in advance
