Instrument cluster voltage regulator?

Does anyone have any knowledge about the cluster voltage regulator making the instrument needles jump or change readings quickly.
I had a problem with the fuel reading full when the ignition switch was set to run. I have checked the ground at the sending unit and then back through the harness to the cluster with no loss of ground or short to ground. I then pulled the ground from the fuel gauge and placed a jumper to another body ground placing the gauge ground back on the gauge. The needle appeared to read normal for a few seconds then all the gauges began jumping around. I then removed the jumper ground, replaced the factory ground and none of the gauges work properly. Thanks for any help.

The gauge doesn't need a ground to work. The regulator does.
