I have a 2005 sportsman 800 the digital gas gauge quit working this weekend. It does not show up when the atv is cut off and back on. Thanks for the help.

 

maybe a bad sending unit in the tank so it wont read the amount.

 

I dont know its like nothing on the gas gauge shows up like it does not have one at all. I thought there might be a fuse or a wire that got pulled loose. I dont have the owners manual for the ATV i may try to fill the tank up and see if that does anything.

 

I have the exact problem on my 2005 sportsman 800. The LCD that used to display the fuel level is blank. This occured after bumping a tree, so I assume a connector got jarred.

 

the book says you have to drasin tank and remove it to test it. w. it empty it should read 5 omhs and 90 ohms when full if you get an erratic reading then its junk and have to replace the whole thing. you use the violet/white and brown wires in the harness to check.

 

Mine was like that when I took it home from the dealer.............Was not the sending unit ......But I forget what they did.........Did not take them long...........I got it fixed with the first service...........I try to remember for you..........Caper.........It will come to me..........LOL....getting old I guess....

 

My wires are red violet and brown (2005 800). The brown is the ground. Anyone know which ones to test?
