OP

Quoted from PinballJeff:

Hello Crew,
Have a strange issue going on with my Mist Ball on BSD. The game has new long range optos that have been tested out on another game. Some work has been done to the 24 opto board and all seems to be working properly. My issue is in test mode "magnet" the game operates perfectly. Game will load the ball, take it back and forth just fine & runs the magnet unloaded fine. When I play a game and get mist ball, the ball will half way across the playfield and drop off the magnet. I've also noticed that while playing it will sometimes just release the ball out of the gate.
The game isn't showing a credit dot and nothing is coming up wrong in test mode. I've gone into switch edges and tested all the switches and found no problems. What's stumping me is why it works fine in test mode (have it probably 20 times and its never dropped the ball), but yet drops it 100% in game play. I've taken a magnet and drawn the ball from one side to the other in switch edge and it doesn't seem to have a dead spot coming across the playfield.
Anyone have any ideas why it works fine in test and doesn't work in game play?
Thanks in advance.
