Hello Friends,
So I spent tons of time restoring a nice Scorpion (1980 Williams system 6, only 1500 made). Colored LEDs in the BG, on top, and underneath, all custom to the original colors (looks like a rainbow skittles explosion now).
Among other things, I purchased 4 complete Flipper replacements from Pinball Life. These are the ones that come complete with the baseplate, and all parts. The issue is, they only come with a single set of EOS/leaf switches, and 3/4 of them need a double stack due to the upper flippers.
So I rebuilt all 4 custom. I resoldered each and every wire one at a time to avoid a mistake. They were all working when I started (and as an FYI - This now has a new Rottendog MPU/controller board in it, and PSU).
After I completed my work, the upper right flipper is unresponsive. The upper right has one layer in the EOS stack with a side "tab". I built it with new parts matching exactly. After failing, I tried rebuilding the EOS stack again using the original parts just for that flipper, thinking I maybe used something a little different. Still didn't work. That side "tab" allows power to touch that flipper, and continue on to the rest of the row to the right of it from what I can tell.
First I looked at the other 3, and saw a reversal in the way the EOS switches were wired to the coil on the other two, so I tried soldering that one wire the same way. Still no workie.
If, in the Diagnostics mode, I manually move that flipper, the screen shows in succession, every switch on that row. An image of the manual with that first row, and the current pics of the upper right wiring job are attached (NM the soldering, I have done it 3x now and it isnt as pretty since it was temp, and will be cleanly redone once resolved).
At this point, I am fairly certain I wired something incorrectly. The upper left is basically a termination point for that line, and a single stack, and works fine. The lower two work fine. The upper right is unique due to that side tab, and basically passing power thru and beyond to the rest of the row.
Please note: I did solder in a new diode that bridges the leafs as you can see in the pic (and it is facing the same way as the orig).
I am hoping that one of two things can happen here:
1) One of you owns a Scorpion, and can take a closeup pic of the upper right flipper from underneath (particularly the white/org wires, and green/org wires, and how they connect to the EOS, etc.) so I can visually try to see what I did wrong.
2) One of you knows System 6 pins with 4 flippers well enough, and can see the schematic and tell me I'm a noob and screwed up x.
Other than that I have done a ton of work on this pin, and it is cool and I want to play it. Two ball lock turns off the lights, starts a siren, and then flashes repeatedly during the MB while a timer builds to reach the jackpot threshold. Same 80s Williams sounds as Stellar Wars, etc. but I enjoy having one in the collection that makes those sounds. Very colorful game now with the LEDs for the kids too.
Pics: Its the very top row in the manual on the attached page. Every switch shows in the diagnostics when I move the flipper, meaning the whole row is affected I assume.
Can anyone lend a hand please?
Thank you!
