Im having quite a bit of trouble figuring this one out. The f5 fuse (which goes to the power supply board) keeps blowing. I have three different power supplies and they work correctly in my mars god of war. Does anyone have any suggestions about what I should be looking for to troubleshoot this problem? I couldnt track down an online manual for the game, but I have a printed one for my Mars, so I should be able to compare some things. Im not sure if this helps any, but I unplugged the MPU and it didnt blow the fuse. Powered it down and then plugged it back in and then it blew the fuse.

I was fully working for a few days, then started doing this stuff. Very fun game btw! Thanks in advance for any help you can provide.

Quoted from Tsskinne:

Hey jdoz, it sounds similar to what my black knight was doing when I got it, I have the letter of what was repaired on the board at home, I'll check it after school today. I remember it was essentially some connectors on the CPU, and maybe a transistor or something pretty simple like that on the boards, but again let you know for sure later tonight, wont be home until late though.

That would be awesome. Thanks! I have the rotten dog mpu in the mars, so Ill swap that out for now and see what happens.

Nope, it has that weird auxiliary board that seems like a pain to mess with. It has legs like a rom, but its just a connector on the board.

Thank you very much for the image. I switched to the repro MPU and it hasnt blown the fuse again. I notice on your circled F5 fuse, its a 7.5amp. The fuse cover on the game says its a 5amp slow blow. Maybe thats part of the problem?
