My fuel gauge started showing way above full all the time.  As soon as I turn the key the fuel gauge reflects over the full pointer.  I remove the gauge from the dash and tested it in a stand alone environment.  The results are attached.  To get the full reading I put 12 vdc as follows pos to the I (input) and neg to G (ground) middle post.  To get the  empty reading I jumped across the S (signal) to the Ground.  

I have attached screen shots of the full and empty readings.  The full is what my fuel gauges looks like all the time in the coach.  

Would this indicate a bad gauge?  There is a resistor between the I and the S don't know what the value should be and if that has gone bad somehow.  Honestly I would love this to be my problem as opposed to dropping the fuel tank and changing the sending unit.
