I do CJs
Even New stuff can be Bad!
I am now attempting to find you a wiring diagram of the system so you can trace thru it.
In the mean time :
Disconnect the sender wire, if it's just one wire (on CJs it's pink)
poke a nail or similar conductive item in the connector and ground it to a good ground (engine)
Your gauge should peg out to MEGA HOT!
This will confirm the gauge does work. Or Not. Or it's in the wiring going to it
If your system has more than one wire to the sender--Wait until I get you the diagram lets see what's what on your Jeep
