I like to work in MS-Paint on JPG's - I show a snippet of (ipdb) schema. All Relays are mounted the same way: Transformer-Powerside -> -> here the wire R-Y-W -> Coil on Relay -> wires and switches -> wire YELLOW -> Transformer-Return-Side (the well known Transformer-Lug-YELLOW).
"Marked green" works in Your pin: You bang a tilt -> Tilt-Relay pulls-in (establishes Self-Hold-Corrent) -> through (encircled green) "longtime-closed" Switch on Tilt-Relay -> Ball-Index-Relay also pulls and pulls (our DDD) -> the pin can do the stepping to next player / next ball.
"Marked-orange" is our test for "EEE or FFF ?" -> You pressed the armature on Ball-Index-Relay - the moved armature activates some switches - it should close its "Self-Hold-Switch, Switch-A on the Relay, encircled-orange-1" ->
FFF would / does show: There IS connection through the wires AND the (encircled-orange-2) Make-and-Brake-Switch on Outhole-Relay. At the time when You PLAY a given Ball - at this time the Outhole-Relay "does not pull / should not pull" - "encircled-orange-2 is as shown in the snippet".
GGG shows: NO connection -> I want to have a closer look at "encircled-orange-2".
When we have fixed it (You press anchor-plate on Ball-Index-Relay and let go -> Ball-Index-Relay pulls and keeeps-on pulling (FFF) - when we have fixed this -> we will have a look at "Initial current shall flow (my "marked-red" stuff.
To do some work on "marked-orange" -> http://mirror2.ipdb.org/files/2253/Williams_1976_Space_Mission_Instruction_Manual_Jan_1976_no_schematics.pdf -> page-27 (ori-25) -> Outhole-Relay -> Switch-C - when Relay is NOT pulling: There must be a good connection "Middle-Blade-Yellow Outer-Blade-Green-Black". Please check this switch - also look for "when the pin idles after reset is done -> Outhole-Relay shall NOT keep-on pulling".
An information from schema: "Due to wire shortages beyond our control, some wire colors may be other than indicated on wiring diagram" - so: Look for the SWITCH - color of wires soldered-on might be other than indicated in the schema ...
Want to investigate on "Initial currrent shall flow to Coil on Ball-Index-Relay (my "red" stuff)" ?
-> manual-page-25 -> Extraball-Relay -> Switch-B.
-> manual-page-23 -> lower right corner of the unit -> "encircled 1". IF (if) You have the "Lights indicate the position of the Unit" -> "3 grounded wipers" means: most likely the wiper HAS connection to -> -> transformer-lug-YELLOW.
(((I do not like the term "grounded wiper" - I would prefer "wiper has connection to transformer-lug-YELLOW")))
