Instrument cluster lights 70 swinger non- rallye

So I'm piecing my dash back together after a rebuild. I'm bench testing the cluster. I've grounded the cluster to a battery. I have turn signals, e flashers, the highheam light, and the oil light. I can not get the cluster lights to work. runnings lights and headlights function New headlight switch, new light bulbs, a cleaned and a polished printed circuit board. Fuse test good and the same fuse powers other stuff that works fine. What in the hell am I missing?
