heres a quick tip to get it workin again.....loosen top mount on handlebars....remove airbox and fuel sender....take tin cover off of part where arm pivots....bend little tab where the linkage looks like it moves on the coils of wire....the key is to bend it so it has a slight pressure on the coils.....test pluggin in and starting the sled move linkage up and down to watch your gauge move....had the same problem on my srx worked for 3 years no now problem and it didnt cost me a cent
