Old barn find however remarkably the back glass is nice, playfield not so much. I've decided I would fix it to save it. There are a couple of coils that are complete melted toast and there is no schematic or manual on IPMD. Can anyone help with a schematic? Also, I believe it is the bonus unit on the bottom of the playfield? I need to know the size coil for that stepper that has the blue/pink wire and red/white wires and also the size coil on the spinner relay. Can anyone help? Thanks!
