I've owned this game for a year now and every 10 or so games, it seems to randomly slam tilt. There is no rhyme or reason. Sometimes it occurs 2 minutes after the game was turned on, other times after 30 minutes. Sometimes never.
As far as I know, there are two slam tilt switches in the game. The one under the center of the playfield is open by default and the contact switches are very far apart. It would impossible to activate this if you threw the game across the room.
The other slam tilt is the one to the left of the coin area that relies on a rolling ball to break a closed switch. This one I've used a leaf adjuster to push closed as tightly as possible. It doesn't move at all and the contact is pretty good. I would ideally like to short this closed permanently but I'm not entirely sure which of the 3 wires to solder together. At least then I can be absolutely sure it's not this switch. And then if that's the case, anything to check elsewhere? Thanks for the help!
