Checked it last night after driving the reading at the sender was 150 Ohm, which should depict about 103*C / 217* F
I'll move onto checking the wires and gauge. (My bet is on a bad gauge )

Last week my Fiero started to overheat so I turned around and went back to the house. Checked it later and it was just that the dumb needle moved. It really fooled whereas two years ago I had done the rewiring to to stop the peging! Guess it's a lil lose. Anyway way back when I had made a tiny pin hole in clear plastic, so I was able to slip a thin 22g wire in and set back where it belonged without pulling the whole cluster.
