Ok, here we go. I'm in trouble.
I 'm under playfield swap. This game have never been on before this because it came with missing parts.
I have installed Pascals PI-80 board and the game is running now. Anyway it keeps getting Coil error 1 with A3-J5 unplugged. It should reflect to knocker coil. Knocker coil was burned and I chsnged it to new one but still the error when A3-J5 is connected. It gives also some weard c.cen.tr switch 37 error. I don't even find that switch from manual.
Measured DTS8 and QS8 from Pascals board and they should be fine.
Ps.
Quite pain in the ass to adjust those hole up-kickers to have stenght enough to kick ball out of hole. Any tips?
