I'm working on GnR and all that happens is the GI comes on and it makes weird sounds. Fuses F1 and F2 also blow but not right away. They take 30+ seconds to glow red and blow. I'm getting good voltage to the board and out of the board. DB1 and all caps are good. The board has also been tested and is working good in another game. When I disconnect CN6 the fuses don't blow. I'm stumped.
