Quoted from LOTR_breath:
Can you post a video of in game play? Not exactly sure what problem you're having. Also, the magnet does not appear to be flush with the playfield. The ball should roll off and down the playfield when the magnet releases.
So when in a game it will only latch to the magnet when I adjust it to hold for X milliseconds after striking the captive ball. This is a setting that seems to activate the magnet after every hit, regardless of the game being ready to activate a ball. It holds it for a second then releases. It releases even if the ball is ready to be locked. To me it seems like it just never triggers that magnetic switch #63. I can place a ball by hand right on the magnet and it will not activate. Not sure the exact number, but after so many games or triggers without activating the games will display an error. Something like "Check switch 63. Out of service." I can reset it, but that doesn't help.
You are correct it's a little bit down. I guess to me that's a secondary issue. When the settings are as described above, the ball will catch and roll off 90% of the time. The 10% of the time it will catch then get stuck and go though a ball search. During the ball search process is the only time I've seen a ball load into the coffin. If it's ready to lock a ball the ball will say in the coffin, otherwise the game will just kick it back out.
