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.
Quoted from terryb:If it's F1 and F2 on the power supply board then your 5 volt fuses are blowing, which would keep the cpu from booting. Test DB1 for a short.
I tested DB1 and it's good. The power supply works fine in another game.
Quoted from terryb:Pull all of the connectors that carry 5 volts to other parts of the game. See if the fuses blow. If not then add the connectors back one at a time.
The fuses don't blow when CN6 (on the power supply) is disconnected. Instead of disconnecting CN6 I pulled CN17 from the CPU and CN4 from the Sound Board. Even with both of those (CN17 and CN4) disconnected the game still blows the fuses. CN17 and CN4 are the only ones that CN6 carries the 5v to. Do you have any other advice on what I might be able to try? Thanks.
