'08 B-125 Gas Gauge/Meter (From Tank To Dial)
Others have run into problems with the gas gauge on their Buddy series scooter. I'm finally ready to tackle the issue and would like outside support. My first question for those with experience:
From the tank all the way to the dial ... how does this system operate?
Sidenote: I've inspected the float arm and it *appears* to be just fine. My thought is that maybe there's a fuse somewhere in-line?

Well in our case it's not working at all and where my wife is comfortable with using a trip meter, this scooter doesn't have one
So we're wanting to at least get it operating to some degree again.

I had a Kymco People 250 that was similar to the Buddy gauge. It had two tanks and the float was in the lower one. The upper tank was larger than the lower tank and would last for ~75 miles and lower one ~25 miles. The gauge would indicate full for ~85 miles and then quickly drop to zero in ~35 miles.
The Buddy gauge does the following;
Full for ~15 miles.
Linear drop for ~65 miles.
Enters the red zone (1/4 tank) and falls to empty in ~15 miles.
At this point, one gallon fills the tank.
I don't sweat the empty designation unless I'm at least 30 miles from a gas station.
Non-linearity is a hallmark of 'scoot fuel gauges(?).

Guys,
Your responses are quite informative (and will help others) but for MY purposes, you're MISSING THE POINT
Our gauge isn't working AT ALL. When I say "linear" what I'm meaning to suggest is that I'd like to know all of the prospective failure points that I should check to see if anything is broken or unresponsive.
Help me at least get this thing working again, badly or not

Hook it up to a multimeter and see if the value is changing as you sweep the arm through it's range of travel.

Is the buddy sender like the generic Chinese ones?

JohnKiniston is right, the sending unit in the tank sends a variable voltage (amperage, wattage?) as the arm moves up and down. So unless there is a fuse blown the failure could be the sending unit, a shorted wire somewhere, a bad ground, a loose connection somewhere, or a bad gauge.
Helpful, eh?
