    hey all. Having an issue with WPT its driving me insane. When you press flipper buttons ace in the hole switch is triggered as if you hit ace in the hole. Doesnt matter if playfield is up or down. It also triggers when a ball is ejected into shooter lane. What fixes the issue is when i touch the metal lock in the back of the playfield with my finger. Any thoughts on where to start? it seems like a ground issue? I dunno im kinda lost on how to fix it. THanks for any help

    It sounds like a vibration issue to me. When you stick your finger on the lock pins, you're kind of holding the whole ace in the hole unit still. It stabilizes the thing and prevents it from shaking as much. Have you inspected the opto wiring for that area to make sure it's sturdy?

    When I put my fingers on the back of the ace in the hole shot it stops triggering. Not the actual jail bars. Like the scoop part where the ball sits when the play field is up.

    Alright, but you're still holding the unit steady. It's switch 59, which is an opto, that triggers ace in the hole. If the opto switch is triggering, it means the beam is getting interrupted somehow. It could be the transmitter side stops lining up perfectly with the receiver side. It could be a wire isn't making good contact with one side, so it's not powered. Whatever is causing it, the light is not getting from side A to B. You need to pull your playfield up and look at those two opto boards, and make sure they're screwed in nice and tight and that the wiring is well soldered to the board.

    Edit: I say soldered, but they're weird boards and I don't have a WPT in front of me. They may be plugs. Either way, the wires need to be making good contact.

    everything was tight and all the wires were connected with good solder joints.

    Seems like it’s the bottom opto board. Crap part is I can’t find a replacement for it on any site.

    Pinball Center has one, but it's $$$$.

    I had the same issue. It turned out to be a broken solder joint. Check the board for this, as you may not need a new one.

    My Ace in the whole locks the ball as it should BUT, it realeases it after 5 seconds again, so you get two balls in play...? You can the drain it, but it should be working right and hold the ball until the multiball is activated... Do anyone have a sugestion what could be wrong?
