Gas Gauge went dead - 82 GS750E

[Guest]

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?

where it plugs into main harness under tank is where i would start. wiggle wires while watching guage

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.

again, you might find help searching the technical threads.

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.
