    I need help with my cluster

    I have the 323 gt digital cluster and its starting to go out. I was wondering if anyone has had any luck with repairing the clusters or a schematic of the cluster's circuitry would help me. I took it out and touched all of the solder connections on the back. So far its been ok but I am still skeptical about it being fixed. I think that the frequency crystal is going bad. Im going to replace it this week.

      Ok well I will start out by the first symptom. I was sitting at a light and looked down at my cluster and saw the temp up all the way, the fuel up all the way, and the MPH at 120 when I was sitting at the light. I shut the car off and turned it on. It was ok till I started driving and then it started flickering and then blank. I got home shut the car off and started it again, the cluster was fine. The next day the cluster kept freezing so I took it out at work and resoldered the back board and took it apart and cleaned the corrosion off of the board and fixed some soldering in there. Since then it has been fine until today when I started the car up and noticed while I was driving that the MPH was staying around 20 MPH when I was doing like 60. I tried turning the car off and on and it will not fix it. Speedo cable is fine since the odometer is spinning at the rate that it should. I just would like to know if anyone has the FSM and if it has any schematic for the cluster so I can fix it. I am pretty electronically inclined since I work on aviation electronics. Please any help is greatly appreciated

                For future reference, the non turbo models with the tach, are not the same. They will work, but wheres the fun of going into boost, and not having your cluster tell you your in boost? :D
