Hey guys, trying to debug a stellar wars. I just installed the MPU327 combo board, but when I run the test I am required to press SW1 diagnostic which does nothing. Which switch is this? IS there a switch matrix somewhere? I don't see it in the schematic. I do is the switch goes through IC24 and then finally to IC1 at pin 6, but I am not reading continuity between anything while closed/open. So either something is disconnected, or I'm not actually on SW1. Any advise would be greatly appreciated
