help please
 

I own an all original 1964 corvette. In doing restoration of the dash gauge panel I have run into an electrical problem. All gauges worked prior to removing the gauge cluster. After replacing it some of the gauges do not work. I tested the fuse box and the fuse marked "panel" does not light up the tester. I'm sure threre-in lies the problem. I don't know enough to remedy the problem. Anyone have any ideas to help me?

Thanks
