This is a bit of a longshot, as I am still trying to find a schematic and manual for the machine. My Hayburners II lost power during a game and has become frozen mid-game and will not reset/restart. All the switches/targets are non-responsive, along with the shooter. Under the playfield, nothing seems to stick out on a manual reset option of some sort? I've even tried looking at the individual relays to see if one has become stuck open or shut with no luck.
Any ideas on how to proceed would be appreciated. I've been flying blind so far with not a clue on how any of the pieces work (given lack of schematics).
