I recently got done replacing the thermostat and I had the thermostat sensor unplugged without unplugging the negative terminal of the battery. Prior to this job the gauges were all working. The TJ starts fine and everything works, including the cluster lights, except the gauges. As of now, I have checked the ground under the driver side speaker, the ground behind the gauge cluster, and some grounds in the engine bay. I've pulled the cluster and cleaned the pins. I've checked all of my fuses behind the glovebox and in the engine bay. All I've been able to find is that I'm not getting any voltage where fuse 12(panel lamps) behind the glovebox goes. It's not the fuse because I've replaced it. My multimeter reads 0V when putting it into the fuse box. There's two orange and one tan wire coming out of it. I traced it to the right plug that goes into the gauge cluster and I don't seem to be getting any voltage at that plug either. I'm loosing voltage somewhere and I'm having trouble locating it. Could this have anything to do with the thermostat sensor being unplugged?
