67 Dart: Temp and gas gauges dead.

Thanks. Keep in mind that while some terminology seems simple to some of us, guys like me don’t immediately understand.
The gauges moved when tested out of the car. Why wouldn’t they work when mounted in place?

If you fed it power as it normally should have been, the ignition "run" line to the cluster, the gauges run off the IVR. If it's bad, it would not feed power to the gauges. Not sure, otherwise, unless, just bad connection. As I said the studs can lose contact with the board traces, as well
