Quoted from fusion301:Fixed as of now - What I think was the problem: Coil wire was pinched over time by solenoid and shorted, blowing the fuse for that entire row. New fuse, some soldering etc, a lot of sweat and 2 beers got it done.
Machine is in decent shape - inside cabinet needs some serious cleaning under playfield, black carbon dust and smells like smoke, ramps need cleaning, but otherwise we're going to get this new pinhead dialed in nicely. Trough Opto boards need to be taken out and cleaned - throwing some random errors, but the main issue was that bare wire Im pretty certain.
Super cool of you Fusion this site is awesome!
