Here is what I have tried. Sanded cluster connection points to bare metal. Tried clipping onto housing (trying to check gauge ground)- nothing. How does everyone get gauges to ground? Is there a trick to this?

RED: Obviously it's not grounded in the sense that there is not a good GROUND PATH all the way to the battery. SO just think it thru and study the path from gauge back pad and be sure all touch points are clean metal, all screws joints are tight and all ground wire connections are clean and tight. Chris you have either not sanded the correct spots or the spots you sanded are not touching good enough or are touching unsanded. I don't know how the cluster is built or attached to dash, but you do. Be sure the dash itself is grounded to that body. ALSO your comment ...."and gauge frame is grounded"...what exactly do you mean? how is it grounded? by a test wire or normal mounting? This is taking too long. Touch/fasten a ground test wire to gauge frame, mount gauge in cluster, touch other end of wire to various places to see where ground is or isn't, start right next to gauge and move outward. Why can't you take out the whole cluster and get gauge working as mounted, then you know that all cluster metal is grounded to gauge? Then sand where cluster mounts to dash?

GREEN: What housing? If you are "clipping" onto gauge housing when outside of cluster and same clip place when inside (mounted to) cluster, it has to still work. Provided that the other end of the test ground wire has not been moved from wherever you have it attached. You can not change methods or connection spots during a test.
