I had bought an '84 Corvette last November. It had a few issues engine wise and a few electrical wise. One of which was the dashboard instrument lights weren't working. I did some research on it and found out that it was a simple burned connector. I took the cluster out and sure enough, that was the problem. Cleaned up the area and replaced the solder. Here is the final results of the cluster, back in the car, in working order. :)
