Okay this is getting ridiculus!
Sending units are operating with in guidelines (according to how many ohms they are to be sending out)
Fuses and fuse panel are all fine.
Plopped in new gauges, and they worked fine, for about 30 seconds, and then right back to where I was to start with.
There has GOT to be a wiring issue somewhere between the fuse panel, and the gauge cluster. (not really looking forward to digging into that).
The only thing I can think of is the fact that 6 months ago some one tried to help themselves to the cheap stereo I had in the jeep, and made a real mess of the in dash wires, but at the time, it appeared all that was damaged was the stereo/ speaker wires, along with a wire that fed juice to the lights mounted on the windsheild tabs.
So I guess my next step is to put the voltometer into the plug sockets that clip to the back of the gauge cluster. At least at that point, if I find anything, I will know exactly which wires to check from the cluster back to the fuse panel.
At this point,I think it would be easier to put her out to pasture and pick up a early 2000's model, take what I can off of the 93, and go from there.
