Gas guage/water temp guage

I have a 1983 CJ5 and both my gas guage and water temp guage dont work, is there a fuse that is for both of these that could've gone out? I need to fix this soon so any help is greatly appreciated

check the instrument cluster fuse first if not blown then you have a hot wire (red) coming into the back of the fuel gauge check it for fire as it feeds power to the fuel gauge and the temp gauge, if you have power thru the wire then make sure the instrument cluster is grounded, if you have both then the gauges are both bad
there are some very good articles on here as to gauge repairs

There is a fuse for the gauges.
But most of the time, it's the voltage regulator built into the fuel gauge that has gone out...

Yes, I didn't misspeak, there is a voltage regulator built into the fuel gauge, and it knocks back the voltage for the guages to work with...

There is a user named John Strenk here, and he has a WONDERFUL page or two on how to diagnose, repair, replace tune and work with these gauges.
If I were you, I'd look him up and ask him directly for links to his pages! It's REALLY GOOD STUFF, probably the best write up and pictures you can find now on the trouble prone Jeep cluster gauges...
