temperature gauge not working
 
I just spent considerable time reading old threads on this topic and need someone to put this in terms that I can comprehend. Admittedly I have no experience with multimeters, ohms, continuity, or other procedures and terms discussed in past threads. I did learn that I can disconnect the sending wire and ground it and the meter should peg hot if the sender is good. But if it doesn't, who can tell me in common terms what I check next and how? Do I check something in the wiring or on the back of the gauge cluster, what? Please, someone dumb this down for me. THANKS

"I did learn that I can disconnect the sending wire and ground it and the meter should peg hot if the sender is good."

If you disconnect the wire from the sender you will not see the gauge do anything. Disconnect wire at the sender then test sender to ground for continuity. If it passes, sender should be good. Testing the gauge would be wire to ground at a certain Ohm resistance for that gauge. Common problem is wires get old, brittle, burned and ground themselves to something.

Does that help?

Or the resistor on the back of your gauge could be faulty...good info on resistors with pics here.
