Oil pressure/volt meter troubles

Hi all, I have the dual oil pressure/volt gauge in my car, what would be the most common reason that it's not working? It is seated properly into the dash and I couldn't find a fuse specifically for that gauge in the box. Bad connection or broken pathway on the circuit board in the back of the gauge cluster? Any help is always appreciated.

If the other small gauge(temp), and the idiot lights work, then the fuse would not be the problem. First question is, did it ever work? One thing that comes to my mind is if someone swapped a Spyder gauge cluster into a base model car, the wiring would not match up.
If the needles used to work and now they don't, it very well could be a broken trace on the circuit board, most likely the ignition + feed.

They did work when I bought the car, then I swapped out the dash for another but kept the original circuit board. When I refit the wires in the back, some didn't have the same amount of play in then, not as much slack, maybe that's making it have a poor connection at the main plug-in in the back? Hopefully. I'll be crawling under there again when the snow is off the ground and Monza!

I've seen two possible issues with these gauge cluster issues, cracks in the printed wiring especially at the bends where the plug goes in and folds the copper tabs. The clips that snap into the the cluster and make connection with printed wiring and supposedly grip the studs on the back of the gauge can be problematic also, clean and re-tension. Sounds like loss of power or ground connection to that gauge unit.
