    I've found that after i disconnect my battery & reconnect it, my gas gauge stops for working for a few hours. Then it seems to just start working again.

    Is this normal?

    Its kind of an annoyance as I disconnect my battery at the end of my weekend to save it from draining.

    Not normal for anything I've ever owned. What year and model is it? What happens if you ground the fuel sender wire while it's acting up?

    Its probably loose at its connections to the printed circuit board. Factory used stamp tin speedy nuts there. a little vibration or temp change will make or break the connection.
    Depending on what panel you have and your ability you might reach up in there with a 1/4 drive disc ratchet and 3/8 socket to tighten the nuts a little.
    Any way you go about it disconnect the neg' battery cable first.

    Your battery shoud never drain , if it does either the battery is bad or there is something left on to drain it , i can leave my dart for three weeks and it will turn over with lots of power. As far as the fuel gauge sounds like a bad ground at the tank .

    Not normal. Does the temp gauge do the same thing?'

    FIRST order of business is to FIND THE DRAIN

    Take a test lamp and hook in series with the disconnected battery ground. Remove fuses one at a time and see if the drain goes away. If not, disconnect the alternator output stud and see if that kills it.

    I'm positive its not the battery. Once in awhile i'll forget to unhook the cables and then 2-3 weeks later my battery will have gone bad and the parts store will swap it out.

    Do you have an alarm on the car ? I let my car sit for a month at times starts right up . You must have something hooked up pulling power when key is off
