I am in the process of rebuilding a gottlieb victory, step by step I got more things to work, but all of a sudden all of the playfield lights stopped working.

I had the machine at the point where it booted into attract mode by replacing and socketing z12 trough z14, then I ran the mpu with only power and displays connected, after reconnecting the lights stopped working, obviously if thought the fuse was blown, but it isn't....

The display still runs as in attract mode, and the big lights still work, just none of the playfield lights, and I really can't figure out what is wrong. (I even replaced the entire playfield, as I have to victory's but still no lights)

Any help would be highly appreciated

Yup game is fully functional, test mode runs all light test, but none come up, voltages are good, I'm guessing something is burned on the mpu, but I have no clue where to look

Pffff a bad ground wire should've known, well at least it was an easy fix problem solved!
