Electronics are my weak point when it comes time to pinball games. I just started putting my T2 that I am restoring back together and was looking at the boards for the first time in a few years. This was a heavily routed game and wanted to know if there is anything to look for in the boards I would hate to get the whole game back together and find out the boards are shot. I dont see any broken tracers but definitely some crispness on the back of one of the boards. Any advice would be appreciated
