Testing gauges on 74 Charger?

Testing gauges on 74 Charger? - 02/27/18 03:49 AM

My buddy bought a used cluster for a charger last year at Carlisle and wants to test the gauges before he puts it in the car. I know with it in the car you can ground the sender wire and the gauge will sweep full to the right. Is there a way to test with no voltage? A certain ohms resistance?

put 2 AA batteries in series.
wire them to the gauge.
give it a sec to start moving. it isn't instant. assuming you got the pos and neg right it should move about to half way on any of them.
