    CJ gauges are dead

    Is there a common fuse for all the gages? None of mine work, not even the warning lights, 1981 CJ7.

    The fuse box on the driver side bulkhead should have fuse description. The gauges have a common ground.

    Re: CJ gauges are dead

    Our Jeep CJ's can be full of electrical gremlins, and not from just what the P.O. did.
    CJ gauges are electrically grounded to the Speedometer housing by their physical contact, the Speedometer which in turn is grounded to the steel dashboard by contact, then to the body tub. Now IF it exists, a grounding strap from the negative battery terminal to the body tub is how the factory and many have addressed grounding issues. Further steel is not the best conductor of electricty. Some, myself included have gone the extra step of adding a negative bus bar and copper wiring to address further grounding issues. Over the years I've found a couple of excellent write ups about gauges and electrical in general that I commend to your reading;

    Quick fixes are so named for how long they stay fixed.
    If you run out of gas, no matter which way you decide to push, the closest gas station will always be uphill and in the other direction. Corollary: The likelihood of running out increases when all of the nearby gas stations are closed.
    The parts shop that stocks part for Skylab II will not have parts for our year/model of Jeep.
