I am mainly an EM person. I own one SS, Data East Secret Service. I was working on the pop bumper switches last night trying to get them to be more responsive. Being an EM guy I was working with the machine powered on. You guessed it. I shorted the switch against one of the coil lugs for the blue pop bumper. Fuse blew, etc. Now when I power the game on everything works except the blue pop bumper. It no longer fires, and it overheats with the switch open causing the 5 amp slow blow fuse to blow mounted in the head on the right side. I'm looking for advice before buying a new coil. Is it the coil, one of the diodes or something on the CPU board?
I also have a second question concerning the F5 and F6 fuses on the Power Supply Board. In the head next to the board there's a fuse block diagram that shows these should be 2 1/2 and 7 amp slow blow fuses. The game schematic shows them as something else (I think 5 and 7 amp slow blow), and another diagram I got off the internet shows them as 3 and 8 amp slow blow fuses. Does anyone know what they really should be?
