My BTTF machine blows a fuse during multiball. I've traced the fuse to J6 on the PPB board. I've looked at the schematics and the wiring doesn't seem right. Can someone take a picture of their plug at J6? I really appreciate it. My PPB board is a Rottendog replacement. The fuse that blows is F7 which according to the Rottendog schematics is J6 on the board. I have tried two RD boards and the same thing happens. My first step to resolving this issue is to make sure J6 is wired properly. As it stands, the plug has never been tampered with.

I really appreciate your advice!
