Hi Pinside,

Hoping you can help point me in the right direction for this one. The issues I am having is that when I have 1 or more balls locked in the castle lock and the game tries to release just 1 of those balls it releases all of them at the same time. The other issue the game has is when a certain combination of the 3 mid bank targets are hit at the same time the game thinks there is a ball in the crypt popper. I've had this game for quite some time and both of these things have been going on for as long as I can remember, just now getting around to fixing it. In the switch test menu I started hitting the mid 3 bank switches in different combinations trying to figure out if it would trigger the crypt popper.

Here are the results:

1. When I press the middle and right switches at the same time the "opto castle 3" switches goes off
2. Right and left switches the "opto crypt popper" goes off
3. All 3 switches pressed at the same time triggers the "mystery hole"
4. Left and middle are normal. Doesn't trigger anything else.

Looks like the wires have been re-soldered to the switches in the mid 3-bank. Sorry for the blurry pic. Wondering if the wires are attached correctly but don't have any reference.

Any ideas were to start?

Thanks guys! I looked at another bank of similar switches in my IJ and it definitely looks like all 3 diodes are reversed. I will swap them around and report back.

I completed swapping the diodes. I still have the same issue. I also tried hitting different switch combos and if I hold some of the middle 3 bank with some of the left 3 bank, several switches get tripped including the bottom pop bumper will go off. Other ideas? Just keep looking for diodes in the wrong direction?

First of all thank you all for helping me! Second, sorry for the grainy pictures. It's the best I can do with what I have at the moment. I tried YeOldPinPlayer's suggestion to go to pinwiki and do the diagnostics. I went through the tests and everything checked out OK on the circuit board side so back to the playfield. I did a lot of stare and compare with other 3 switch banks in games that I have and noticed that all of them have the 2 yellow striped wires going to the bottom lug and to the anode part of the diode. My switches had them attached at the top at the anode end. So both wires and diode were wrong. I had to switch the diodes back and move the wires from the top to the bottom on all 3 switches. Whoever owned it before me must have replaced the switches and attached the wires incorrectly.

Now for the first time in 15+ years it will play correctly (purchased in June 2003), what a slacker, lol!
