Ok, step in the right direction! Everything works when I bench test after I replaced the sender.
I next tried testing with installed wires (key the music)....when gauge is in cluster and gauge frame is grounded I get a little movement. When gauge is NOT in cluster but grounded through a clipped on wire, it works!
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?
