One thing to be aware of is early hh are wired differently than main production games for that kicker. If you changed your rom or boards you may have a mismatch. I added a pascal board and fortunately he has a setting for this, although it took me a bit to figure out that was what was happening.

To be clear u are talking about the kicker from the main PF to the attic correct? According to the repair manuals that is not Q58.

It is hard to find docs on the difference between the demo and main production versions. What is your serial number, it will confirm if you have one or not. If you do it may explain why u have this issue.

Well if u dont have an s on the end of serial then scratch the whole sample thing. It must be a x wire somewhere.
