So up until today, my fuel gauge worked almost flawlessly (under empty still had enough to get me to a gas station). But today I had to pull the cluster to plug in my new speedo cable (up until today that didn't work) and the fuel gauge STILL worked up until the last time (of course the time I got the speedo to work) I plugged in the speedo cable. Now neither my fuel gauge or my battery gauge will even twitch. Fuel gauge is stuck pointing almost straight up and battery gauge is reading "dead" when its obviously not. Any idea guys?

 

try the ground that connects to under the dash left of the steering column
