Thanks for the test procedure cg285. It looks like I have a bad sender unit. I was beginning to suspect that yesterday after I found that the lights did work when grounded. I bought this unit from Classic Parts along with the rest of the colling system parts, but guess that I got a bad one. My local NAPA store will have one for me today by 2:00 though.

Put the new temp sender in without losing a drop of coolant (drained a gallon out of the radiator to lower the water level) and immediately had a Cold light when I turn the key on. That's a first since I've had the truck! I'm sure I'll see the Hot light come on when I crank it, but letting the tread sealant harden before refilling and cranking it. Thanks to this thread, I now understand how this thing works!
