Quoted from dbpbandit:Yep, it's definitely the MCB causing the issue. I switched Red and Ted and sure enough, the problem moved from Red to Ted.
So, I checked it out and I can't seem to find anything wrong with it. However, I did resolder one if the coper coils (not sure of the actual name of these parts) because it looks like it had come lose and someone did a crappy job of repairing it. I also replaced the other resistor (I replaced the originally missing one prior to this) but now, Ted's mouth only opens and closes about half way. Red however is still the same, she wont close her mouth and keep it closed. So basically I went from bad to worse.... I don't have any matching caps but I'll pick some up and replace them next.
Does anyone work on these? Does anyone sell these? just asking, just in case.
Thanks.
When I got my machine it didn't have the issue but after playing the balls off it (pun intended), it shared the same issue. I even went to Rat Shack for new motors and adjusted Red's face and it helped a bit. Reflowing the solder on the board helped much better but I bought a new board for PSPA (they're still in stock) and Red's mouth moved normal/much quicker so glad I bit the bullet. I'm sure someone can get your board going again but I didn't want to be without the game for a few weeks. http://www.pinballspareparts.com.au/a-19159.html
This board is also used in Corvette FWIW.
