I don't have a lot of experience on this era of game. Got the game without any boards except for the lamps board. Bought a Rottendog Rectifier board and a Alltek MPU. I sourced a driver in working condition according to the person I bought it from.
I repined all the connectors. I unplugged everything before booting up, including the displays. I plugged in J2 on the Rectifier, no problem. I plugged in J3 and powered it up and immediately blew F1 and F4 on the rectifier. I believe the J3 feeds the play field and all its components but even if it does I have no clue as to why these blew. Can someone help me take the next step as to what look for as to why these blew or any next steps? Thanks in advance!
