If these two are touching try bending them apart slightly. I can't tell if they are on different levels from the photo.

Hi MNpin66
I am german speaking - I do not fully understand Your description in post-1 (subtleties in the english language (?) ): AAA Intermittent issue, BBB Score-Relay-Coil, CCC fire continuously, DDD Coil on relay keeps jumping.
AAA-1 means sometimes when You toggle-on and start a game You have the fault --- but not always.
AAA-2 means whenever ... the fault ALWAYS shows up.
BBB-1 is the 10-Point-RELAY, BBB-2 is the 100-Point-RELAY, BBB-3 is the 1000-Point-RELAY, BBB-4 is a Score-DRUM (counter, stepper) - which one ?
CCC-1 means pulls and stays pulling
CCC-2 means pulls, let go, pulls, let go, pulls etc. in a "machine-gun tempo, fast, rapidly"
DDD-1 means pulls and stays pulling
DDD-2 means pulls, let go, pulls, let go, pulls etc. in a "machine-gun tempo, fast, rapidly"

Dr_of_Style mentioned the "stuck playfield switches" --- rumours are: "EVERY pin can go through the Start-Up procedure having the playfield disconnected". Yes, playfield switches can be faulty - ALSO stuff in the cabinet and/or Backbox can be faulty. A simple test is: Disconnect the playfield (unplug the Jones plugs) - then do a "Start-Up" --- IF (if) the fault does NOT show up: The problem is most likely on the playfield.

Do You have a schematics - would be VERY helpful, greetings Rolf
