    My 94 C1500 Suburban's gauges all read off. The temp never gets above 120, the voltage reads about 13 (about 9 when alternator is unplugged), gas gauge reads just below half when actually close to empty. Any thoughts? TIA.

    Mine too .. the one I notice most is the temp guage which starts dropping until a gentle tap on the dash brings it back up to where it ought to be

    Do the gauges always read these readings? My gas gauge is quirky too, its pretty common in Chevys...my voltmeter also reads about 13 all the time. I've also heard that a lot of times the circuit boards in the 88-94 trucks crack sometimes and hitting the dash fixes the mfor a while...may need to take the dash paprt to investigate

    Thanks guys. The gauges act "normal" in that they do vary like expected, but just read off. So I know they aren't stuck. The one that concerns me most is the gas gauge. I burnt out the fuel pump cause I ran it out of gas.
