New cluster did not fix the dead Gauge issues HELP

thanks for reply. The IVR sockets are tight, no wiggle. Could you give me an even more dumbed down explanation of how to ground the sending wire to see gauge jump up?
i assume I wouldnt want to hold it too long for fear of blowing/buring out the gauge, right?
As for cluster ground and pigtail, isnt the entire cluster grounded at any one point? Isnt there continuity on the entire board? or are there points at which ground is broken and looks for another mounting screw?
