I have a 1980 Gottlieb Amazing Spider-Man that is blowing the 1/4A SB fuse when turned on. I have a brand new rotten dog power supply and determined that when only the A2 power supply is connected it does not blow. However, I have not yet got this game to boot so I am unsure where to test next. Could a bad MPU cause the display 1/4 amp fuse to blow?
Any help is much appreciated,
