    Gas Gauge went dead - 82 GS750E

    While on a short trip today, my gas gauge went from full (it was) to 3/4 to dead.
    any ideas before I go and start taking things apart?

    I would rather trust my bike to a "QUACK" that KNOWS how to fix it rather than a book worm that THINKS HE KNOWS how to fix it.

      IF you unplug the wires from the tank and put a wire between the two harness connectors the gyage should go up. if it does then the problem is with the wries from the sending unit or the unit itself

        I ran the tests and discovered the gauge is dead and found a replacement on eBay.
        Thanks for the advice.

              it could be electrical it could also be the gauge inside the tank. The gauge on my 84 was always wonky as long as I've owned it. Last year I ran Sea Form through a tank full of fuel to clear the carbs then added some more to a full tank for winter storage, spring riding season arrived and for the first time since the 80's it worked again. I expect the sea foam cleaned the internal gauge, I've no other explanation for it as I did nothing else.
