Does anyone have a complete circuit diagram for the gauge pack? And/or a diagram of the "wiring" runs and component locations? And/or at least a photograph of the board?  I have the 78 electrical troubleshooting manual but that is not specific enough to solve this problem.
 
I have no voltage showing on the voltage gauge and the gen light on but the battery is being charged. Looks to me like a problem with the circuit board, but I hope to figure that out before taking the board out.

I can email you the wiring diagram, which includes a diagram of the PC board for the gauge cluster. Silly question....have you checked ALL of the fuses?

Thanks for the wiring diagrams.
 
After studying them and imagining the worst (a break in a printed circuit), I realized there is a connector on the back of the center gauge printed circuit board. And that there had recently been some work done to connect a new antenna to the radio, right below the connector. Fingers crossed (metaphorically) I took out the glove box, reached in and snapped the loose connector tight.
 
Probelms gone!
 
Thanks again for the quick response.
