I'm learning my way around DE pins. This JP is frustrating me, so someone push me in the right direction. When I got it this pin it wasn't running. I repaired the MPU and got it up and running (bench tested & tested in another DE title). The Xpin PS stopped working (damn surface mount components) and I replaced it with a Rottendog, Pin now up and running with a few issues. The game starts up and tries to eject a ball into the shooter lane but the solenoid doesn't have enough strength to get it out. Most of the PF solenoids don't work either. The PPB is a replacement rottendog that worked before the Xpin PS went tits up. The flipper board had a bunch of bad fuse clips, so I replaced all of them. During a game, when you press the flipper buttons the leds on the flipper board flashes. It acts as if there isn't enough power to make the solenoids fire. Someone point me in a new direction.

Here is a newbie DE question. The header pins at the top right of the cpu. Spec coil switch input CN-18 doesn't have a corresponding female plug.. There is a plug that is keyed to fit 7-segment drive CN-3. Is this correct arrangement?

A little research into DE pins and I find that the coils all have power but the ground is closed upon starting a game. When I start a game and check the coil voltage with the MM connected to cabinet ground I see the voltage at the coils. Where on the DE CPU does the logic close the ground?
