All day it was working fine, and then. Around i'd say 6ish i drove over to hollywood video to meet up with some friends. Just casual driving. Stayed there for id guess 1ish. Got back in my car to drive to the theater and right when i start my car i notice the A/F gauge had no light. So i though it just hasn't warmed up yet so its not reading anything. So i let it sit and wait for it to go through the warmming up process.



Now that its at running tempeture i start driving around and still i get no readings. I havn't even touched anything on the car for a while so i'm clueless as to what it mught be. Bad ground no power iono. I also have a water temp gauge right under it ( not hooked up) but the back light works so i know there HAS to be power toot he A/F.]



any ideas.

 

Maybe it died?



What unit is it? How old is it?



Obviously, check the wiring. If it's seeing 12v. and doesn't work, must be time for a new one.



Nothing lasts forever.
