fuel gauge reading empty when the tanks full, reverse lights not turning on...

Hey ,
i got a 08 sportsman 800, i filled up my tank today and noticed its still says empty, also when im in reverse the lights aren't turning on. could this be a simple fuse problem?
also noticed a slight knock kind of sound when i first hit the throtle. is this normarl?

First thing i would do is get a light and see if the float inside the tank is stuck...I cant remember exactly how the fuel gauage works, but i would look in there.

The reverse lights are not reverse lights unless you have made them that way. Did they have that mod before and now they are not working? Because if its stock, they wont turn on in reverse.

The knock is hard to say. It is a hollow knock, a ping, and clank,.....its just too hard to say

the knock is coming from somewhere closer to the back more hollow the a ping or clank, id compare it to when my u joint was worn on my truck, makes the same noise if you've ever heard that before.

The fuel sending unit has sliding gauge on it. First check the float. Then remove the entire fuel sending unit/fuel pump. look carefully at the sliding gauge. Make sure it touching the board. Make sure the coiled up wire is fine. Start their. Let me know how you made out.
