Gauges have a mind of their own

All of my gauges have a mind of their own except for my speedo, tach, and clock. All of the other gauges are maxed out except for my fuel gauge that floats back and forth. Any one know what could be the cause? Do they all share a common ground that is bad? Or do they just need to be replaced? Any Ideas?

thats just what they do, coupled with the lights working whenever they want to (fixed that one this week)

edit: obviously there is a solution to this, hopefully someone can shed some helpful light on the subject

I think the ground is common. There was a write up about how to fix this a while back - it might be in the "stickies" at the top of the page.

Anyhow, what I did to mine is, take out the gage cluster. They all come in one unit from the dash. Be careful cuz they bolt onto a printed circuit board. Just unscrew the cluster from the dash, slide it out carefully, and unplug the connector from the cluster.

Once you have it out, you can see on the back where the gages screw into the printed circuit board. Unscrew them.

You need to clean all the electrical contacts on the board, on the gages, and inside the connector. Every place where a gage screws into the circuit board is an electrical contact. Get them nice and shiny - I used 400-grit wet-dry sandpaper.

Put it all back together. I did this and never a problem since. Even the dash lights are brighter!

oldtime_ironman we are a dynamic duo on these posts lately I seen! Here is the link for that writeup w/ pics mentioned above... http://www.jeepforum.com/forum/f12/r...er-how-991307/. Here is a link to a 93' YJ manual that has all the diagnostic info you would probably need. http://www.scribd.com/doc/13985775/M...cina-YjXj-1993. Pages 14-22 are what you are looking for I believe.

The sanding helped me bring back every gauge but the fuel. The ground for my fuel gauge was so corroded it was not funny. It's also located in that spot in the middle of your back that you could never touch unless you dislocate a shoulder. I could have saved myself alot of time by un-doing the clip behind the driver side rear tire, splice into ground, and reground it to some bolt. That was really all that was necassary for me in the end... but F*&K it, I go for the gusto and removed the whole ****ing tank to cut a door!

LOL yeah I'm just trying to make sure my jeep is perfect before winter. I had to do my ground wire where it comes out of the tank itself.

RV, those are the links that Edgy gave ya. The guy walks you through it step-by step with pics. Be sure to check that out.
