Hi everybody, I have officially joined the Haunted House owner's club, took the excellent example that SunKing wrote up previously on this forum (and posted lots of details on another thread, he did just a beautiful job of rebuilding the mechanics and getting the playfield from BAD shape to back to near excellent condition in my opinion). The only things the machine really needed were:
1) some exterior cabinet work; Brad did a really smart job of taking a terrible situation and making it look good with the red "blood" effect ("before" and "after" photos below), my wife thought I should just do the same on the other side which I considered but decided against (FIXED - filled in things a bit, sanded cabinet, painted by hand and put in my own "lighting", does not match the factory paint design but close and is fine until (and if) I want to do a full repaint with templates or a wrap
2) some adjusting of the attic upkicker (FIXED - wound up swapping out the 5195 coil that was not original and going back to the 5194 OEM one, works great)
3) new Secret Passage plastic (FIXED, well soon, ordered one from Europe, here any day!)
4) the sound worked ok but sound quality was pretty bad (FIXED - new $25 Pioneer TS1634R 4-ohm speakers via Amazon sound like a darned IMAX theater compared to the original speakers ... yeah I painted the underside of the cabinet as well, had extra time and paint on my hands)
5) some troubleshooting of the trap door which opens and closes fine BUT opens when a game is started instead of waiting for you to hit the right target combos, then it closes when the game is over ... and opens back up when the next game is started (NOT FIXED, DRIVING ME INSANE).
So I beg, no I plead after spending more than a few days trying to figure out this trap door thing for some help! So here is what I have tried:
1) replaced the driving transistor (but turned out the reading for the original one showed the original one working fine, I just got a strange reading until I completely took it out of the circuit ... brand new transistor behaves the same).
2) double checked the circuit back to the Pascal board (V1.3); the repinning work is excellent (by Brad) and the L16 circuit from the board all the way to the transistor on the playfield works with a completed circuit using my meter.
4) Checked the switches that normally would activate the trap door, no issues (the trap door rollunder and the left lane rollover next to the lower bumper, switches both work, although I noticed that the score increments but there is no sound for the lower left rollover, seems odd since every other switch seems to have sound associated with it)
5) Using the Pascal board you can test each coil individually; well, they all work EXCEPT nothing happens for the L16 test, which of course is the trap door.
6) Using the Pascal board to test the "G" coils ("general" coils common to everything I think?), the VERY first test which shows "Relay" in the upper left score, "9 game" in the upper right, and "G-test" in the lower right activates the trap door coil; I think that is the Game Over relay test (since it activates the trap door I figured it might have something to do with the equation).
And I have cleaned every relay, checked the gaps for every relay, plugged and unplugged everything carefully multiple times, but for the life of me I cannot figure out this one. So if anyone has any tips or info to help with the trap door issue, I would be super grateful. But the machine is beautiful, plays great, and so far I love this pin ... a true classic that I am SO happy to have in my collection. Thanks in advance for any suggestions IMG_3514 (resized).JPGIMG_3512 (resized).JPG
