That's the copper strands in the middle. It's the only conductor in the wire, 
but the body and crimp form an outside conductor.

It's red on some, black on some. I think black was the original version, but it 
makes no functional difference.

Probably more like a spring on one end and pushed against the body on the 
other end.

Yes, this was in response to your post that said that you measured an open 
circuit between the connector and the crimp.

Yes, wire to small spring, to thermistor puck, to body. IIRC, the thermistor is 
a small cylinder, maybe 3/16" dia and 3/16" long.

Okay, good.
