I just installed the new sending unit for the temperature gauge, and it
works fine now.

So in case anyone else has this problem, the resistance of a working sender
is:

COLD:      1000 ohms
HOT:             50 ohms

Measurements were taken with the sender wire diconnected, terminal to
block, with a digital VOM.
