[AMC-List] Temp sending unit question

["Jay" <jciampi@xxxxxxxx>]

My 1966 TSM says that the temp sending unit should read 70 ohms when cold 
and 120 ohms when 212 degrees. I measured my new unit and the old unit after 
removing it from the engine and NEITHER one reads anywhere near 70 ohms 
cold. I get 268 ohms cold with the old one and about 258 ohms on the new 
one. That is reading it from the electrical connector to the brass sensor 
that goes into the block.  What am I doing wrong. The TSM doesn't anything 
about whether the gauge wire has to be  connected to the unit while it is 
screwed into place.
