How does the fuel gauge work on a Polaris?
A tank mounted sending unit produces a variable resistance ground path. The ECM module monitors the current through the sending unit to ground and decides which display circuits to energize to show the fuel level.
What should I do if my gas gauge is not working?
Note that some self-test steps may stop the gas gauge at 1/4, 1/2, and 3/4, as well. Fuel sender test. The fuel sender test should be conducted when the tank is lower than HALF, to prevent fuel splashing. Start by making sure the plug is clean, dry, and free of corrosion. Make sure the pins are straight and that the connector is fully seated.
Why is my fuel gauge not working on my sportsman 800?
So my fuel gauge doesn’t even show up on my 2005 sportsman 800 after digging into it a bit I found the fue sending unit board was broke and that that is the problem.
What are the parts of a gas gauge?
The gas gauge system can be broken down into three basic parts: gauge, sender, and circuit. A fault in one or more of these parts will lead to gas gauge failure. The sending unit is usually part of the Fuel Pump Module : a combination of parts that includes the fuel pump, fuel strainer, fuel filter, and fuel float.

How does a fuel pump work on a gas gauge?
The fuel pump module includes the fuel sending unit, used by the gas gauge to detect and display fuel level. https://www.flickr.com/photos/3ndymion/33556245572. The gas gauge is a relatively simple circuit, but its simplicity means each component is essential to its function.
