Success! Took gauge out of the cluster and found 2 grounding problems.. no ground in gauge cluster because painted and wound wire on sending unit was separated from point of solder . Soldered sending unit and sanded to metal section of gauge cluster and bench test now works. Thanks for all here and your advice. Kevin
