Temperature gauge

[Daky2908]

Hey guys, i have stang 3,8 v6 95' and after changing my coolant and few other things I've noticed this wierd thing with my temperature gauge.. I checked temperature sensor and wiring and everything is fine. Any more tips?

The wire from the sender to the gauge is grounded?

 

[Daky2908]

Yes it is.. Actually its not even touched..

 

[General karthief]

What do you mean 'it's not even touched? It's only one wire, use a test light with the clip on the positive batt cable and touch the connector with the probe (key off) if it lights up the wire is grounded someplace,

Done and everything seems fine with sensor.

Done and everything seems fine with sensor.

Explain please.
Oh, and it's a sender, one wire, talks to the gauge
Sensor, two wires, talks to the computer.
