check the wiring at the temp sensor first (you've done that already of course)

next pull out the sensor and put it in hottish water (50 c) measure the resistance , then put it in hot water (approx 100 c) and again measure the resistance . You'll need to get the exact figures off the net but these should do

190-260 @ 50c
23-30 @ 100c

this will isolate the temp sensor from the overall issue.

If the sensor wire is grounded (ie pull the plug off the small sender on the rad & connect to unpainted metal) then the gauge should move high temp. If not then trace the wire from the gauge & check power to the gauge.
