Newbie here to the forums, i recently did a trade for a ms pacman board, hit assured me it worked before he took it out, guy didn't know anything about how it was connected but that the cab was original, i hooked it up to my pacman and it blew the 1 amp fuses right away, after i took the board out i noticed the diodes where solder together and there was a jumper, does this mean i have to add an sps or can I reverse toda to play in my original cab, I've included a picture since there only diagrams i find online about this
