I recently got my second pin (IJ Williams) and it arrived needing a bit of work. I noticed it was very dark...so I traced the issue back to the J120 and J121 IDC connectors which were totally fried! I got some new (and better) connectors and re-pinned them and the GI and back lights were restored.
However...I noticed that 2 of the playfield lights are not lighting up. Specifically, both the R and L "lites hands of fate" GI lights which are supposed to stay illuminated on ball 1 and I believe once you get INDY. I checked the IDC at J119 and it is super clean, no loose wires, no visual issues on the male or female connectors. I checked the wires for thes groups of lights and the wires are clean running back and forth to each other, but seem to make their way to the coin door? The lite hands of fate illumination seems to be a bit unique...as it is on the illumination PCB but has a 3 prong IDC to connect it to the other side before heading to the front of the machine.
What do you guys think? I stumbled across this thread but there was no official solution posted.
I have checked the fuses, all are good.
I have reseated all ribbon cables.
I have fully inspected under the playfield, all wiring is clean.
I pushed in all EPROMs to ensure they are snug.
I have pushed in the ASIC chip.
I cannot get the lights to illuminate in test mode either, I believe it is supposed to be in the GI menu under coin return.
Any advice is highly appreciated, thank you!
Edit 4/27/2020: Changed the header pins at both J120 and J121 and the lights were restored. Back in business!
