I’ve gotta gv125 2009. Topped up my fuel from half to full and gauge obviously reads full but the needle is no longer moving? Has it froze or something??

The GV sender tends to be a little optimistic sometimes , for example on my GTR it will say full then maybe 30 miles later it drops a bar.
If i am to assume i am riding super economically to get 200+ mile range MPG out of a full 17L tank. I expect 3 bars to drop from full if i use around 5L of it. I am not sure how many miles that is as its been a while since i paid attention to the odo counter lol.
The GV in this case will probably say full until its almost 3/4 left of it, then it should start to move down as the float lowers.
You can always test the fuel sensor like this:
- Full Tank = Ride 10 miles , and go home. Unhook the sensor cable. Test with your meter many OHMS you get from the SENSOR itself.
Report back here. - If you suspect the tank is half-full left
Test ohms of the sensor
Report back here.
Ie. Full was 400 ohms , almost low fuel left was 200 ohms etc… (Example here) these are not actual Hyosung figures. You will get that from your meter,
I will know if your sensor is working or your gauge is fishy or just a harness issue.
Have date with that pocket meter 🙂
