Hi jaybird5619
You have chosen an complicated - late Gottlieb pin to dive into EM-Logic. Theory later - please do: Toggle-off the pin, unplug the main power cord (Safety Reasons). Go to the open Backbox and look into - look towards the player --- see the picture in the JPG - the Player-Unit of "Spirit of 76" in HOME-Position (also called Position-ZERO). Look in Your pin along the axis (towards the player) - an steel ratchet - then milky-white Cam-1, Cam-2, Cam-3, Cam-4 and the last Cam is usually black --- black Cam-5. Cam-5 has ONLY one tooth to activate its switchstack. Manually move the plunger on the unit - do step an step - do another one - do another one --- see when You do steps that the Cam-1, Cam-2, Cam-3, Cam-4 do actuate their switchstack (?) --- this is for "routing points made to the 'appropriate' Players Score-Drums". Do steps, steps --- some 15, 20, 25, 30 steps - do a full revolution and more --- see at a given time the tooth on Cam-5 (FIVE) actuates its switchstack - You have reached and are in Position-ZERO / Home-Position.
(((I believe Your pin was in this Position-Zero - and this is NOT a good position to try to start a new game))). From this Position-Zero count, do some 8 to 15 steps --- it doesnt really matter how many steps - important is: You step AWAY from Position-Zero.
Then plug-in, toggle-on - with an wooden stick press the armature on R-Relay - then take away the wooden stick - DOES the R-Relay stays pulling ? What is the pin doing ? Motor ? AX- and BX-Relay ? other Relays ? Backbox-Lights ? DOES the Player-Unit in the Backbox STEPS FORWARD ? 1,2,3 steps - or maybe many steps reaching (again, on its own stepping) Position-Zero ? Write about the behaviour of Your pin.
Theory: On top of the JPG we see "Player Unit 19, 18, 17, 16, 11, 10, 9, 8" --- the position(s) for to activate the BX-Relay when a game comes to the end. It depends on "is the pin set for 3 balls per play or set for five balls per play --- is it a One- or Two- or Three- or Four-Player-Game". In the left bottom corner I made a list for some positions (Pl (PL) = Player, B = Ball). In the JPG, middle, left we see "encircled green switch, drawn closed P1F" --- Position-Zero is also "Position when Player-1 plays Ball-1 as Cam-1 also activates its switchstack". You wrote about "Score-Drums of Player-1 are illuminated" --- as You have stepped beyond Zero-Position by now - they may be lit or unlit depending on how many steps You have stepped - if Cam-1 is actuating its switchstack - or not actuating.
I have "encircled red" switches on BX-Relay - as Your pin did actuate one direction and actuate other direction the BX-Relay: You had the phenomena of "turning on and off the lights for player 2 and 3". Below the picture of the Player-Unit in the JPG: "encircled brown" is a switch on the motor - Your motor faulty turns - switch gets activated, de-activated etc. - I have "encircled blue" Switch on Dx-Relay and Switch on R-Relay" --- I asked You to push the armature on R-Relay (wooden stick) because I want the Switch on R-Relay OPEN - so we hopefully get rid of "actuating AX-RESET- and BX-RESET-Coils". The "encircled green P5A" is allowed to be closed in Position-ZERO - but I asked You to step on the Player-Unit - away, beyond Position-Zero - so this switch must be open by now.
Please write what Your pin is doing when You have stepped away from Position-Zero (Player-Unit) - plugging-in and toggling-on - then pressing the armature on R-Relay. Greetings Rolf
