I am having a baffling issue. All coils 1 - 8 (High power) do not fire either in play or test. I have eliminated the board because I tested another board from another game (Gilligan's) that works fine. I checked continuity from the connector (J130) to the coils and get continuity, but I check any coil will read on all wires (Violet) and the same on the power in at J107. I do get 72 volts going in at J107 on all wires. Is there a fuse other than what is on the board (F105) I am missing as it's not mentioned in the manual.

Note: All the other coils work fine.

Thanks for any help or suggestion

Oddly the thing is this. I did the ground to tip 102 tab on all the coils 1-8 and all fire correctly. Here is the weird part after doing the ground test the coils work again on their own in test or game play. So right now it is running. Next project now its working on the G.I. connectors on the board and gut it and clean it and LED upgrade.

Anyone have an issue where all the controlled lamps not work with a few stay on all the time along with a number of coils not worling. Plus a section of G.I.'s.

Note I replaced both BR1 & BR2 and the ribbon cable. Plus I reflowed solder on the header for the ribbon. This all worked before I changed out the BR1&2 Only did them as they were original. The game does boot normal with no error. Pictures show the lamps. Pictures shows what it does nothing else. Thanks

Ribbon cable was replaced after the issue started. Also tried another cable as well. Maybe its on the MPU side of the connection I'll have to look further. Maybe resolder the connections again. But check continuity from pins to the areas it goes to and checked good.

Have a SDB board just waiting on a new 12v regulator. The cap went and took that out. If that doesn't work. Will have to get a replacement MPU from Arcadeshop.com they have a new drop in replacement.

I was fortunate to get the other boards from another WCS94 and worked for a short time and now its doing it again. I believe its the 10 opto board. It has had repairs before though I think it failed thus caused a short.

I think the same person worked on another WCS94 I had worked on and the SDB is hacked up along with the wiring under the playfield, that works now well at least it did till I used it to test this machine. Yeah I'm just getting a replacement and not worry about repairing this one. At least they are still available and newer upgrades on them

Anyone come across a WCS94 where it does boot normally, but the display is scrambled, no sound or wrong sounds, left flipper energizes when 50v is activated. What all has been done is Power board completely rebuilt from Chris Hibler, New fliptronics board, The following were replaced after the issue popped up. New MPU with new ASCI, processor and Eprom chips, also replaced all the ribbon cables including the one to the display. It worked great and when it moved something happened and cannot pinpoint the issue. As seen in the pictures as it worked before and now.

Thanks
