Is there a way to test the sending unit that powers the temperature gauge on my 425? The temp needle on my gauge never moves. Or is there a way to test the gauge? Thanks

I checked the ohms on the sending unit and it checked out ok. I grounded the wire from the sending unit and the gauge did not move. I did a search on this web but nothing came up about repairing the dash. Could someone direct me to the posts about the dash repair. Thanks
