[QUOTE=Hitman72;14799513]All of my gauges are reading low (or to the left). I am thinking that maybe the cluster is not getting enough voltage, what can I check?
Or a poor ground:
Improving the Instrument Panel Ground
The ground point for the complete instrument cluster on your XJ or MJ is located up under the driver’s side dash. If you lay on your back and look up under there with a flashlight, without wearing a hat, you will see a black wire attached to a shiny piece of metal almost directly above the hood release knob. The screw will have either a ¼” or 5/16” head on it.
This ground point is responsible for handling the ground circuit for the following items: Dome lamps, Seatbelt and key warning, trans comfort switch, wiper switch, headlamp switch and delay module, fog lamp switch, cargo lamp switch, all instrument panel grounds and illumination, power windows and door locks, cruise control dump valve, and a few more things.
The problem is that where the ground point is located does not have a good contact with the chassis where the ground should be. The solution is simple.
Make up a jumper wire with #10 gauge wire about 10” long. On one end, crimp on a ¼” round wire terminal. On the other end, crimp on a 3/8” round wire terminal.
Remove the screw from the existing ground wire and attach the small terminal of your jumper so that the original wire and your new jumper share the same attaching point, one over the other.
Look above the driver’s side plastic kick panel just forward of the top of the hood release knob. You will see an 8mm stud there. Attach the large terminal end there with a washer and nut over it tightened securely.
**Special note for Comanche owners: Make your jumper wire 12” long and attach it on the driver’s side kick panel close to the fusebox on the 8mm stud.**

thanks for the info will check it out when i have a chance.
however, i have a bigger problem at the moment. My clutch is not working....... when for a 600 mile trip this weekend and had no problems (some of the miles were off-road). Got home and parked the truck for 12 hours, the next morning started and drove fine, parked it again for 24 hours at which point a friend of mine drove it (just around school, he has a manual trans himself so i do not suspect him for doing something wrong). The this morning when i got to the truck the clutch went to the floor and felt very weird. it was hard to put it in gear and shift, after a few minutes of driving i could not stop without killing the engine.
I have not check the master cylinder fluid level yet, what else can i do to help diagnose the problem.
If you have no clutch pedal pressure, the you won't be able to disengage the clutch to shift gears. Check your fluid level and check to see if you can find where it is leaking. You could have a bad slave or line.
