I can't imagine any failure mechanism that would make a reed
switch look like 780 ohms all the time.  I suggest you investigate
other possibilities like a bad cable, etc.  If you told me it
pulsed, but had a high resistance, I would try pulsing it with
a high current like 100 mA to see if there was oxide on the contacts,
etc.
