Hi Dr_of_Style
thanks for the flowers. Facts are: I have never had a look into an old Williams pin. I put the snippets of the schema (post-11) together using MS-Paint and paint.net - result: A complete schema I can use ...
Hi Teamworkers
it is fun to work on a pin AND make some progress. You got nice results. I would like to co-work on a pin - thoughts to discuss, splitting a "test to do": "I do this / look at in the Backbox" - "You do this / look at in the cabinet (or on the playfield)."
If I do not fully understand a sentence You wrote: I MUST ask (to get a 100% understanding) - it would be awful You write "ABC" and I understand "UPZ".
Tests (post-16 and -17): The pin shows action, great. I'd LIKE You to use TWO Jumper-Wires and make a comfortable situation (for starting testing): Jumper-Wire-A comes out of the pin (open Coin Door), the Gator-Clip (Jumper-Wire-A) "in the open" is insulated (paperbag), Jumper-Wire-B comes out ... insulated (paperbag). (((This way you easily can take down the playfield and imitate "Ball rolls here and there")))
"Description-Alpha***" You start a game -> -> pin comes to idle / NO Relay (and such) pulls / sticks. NOW You connect (in the open) Gator-Clip-Jumper-Wire-A PERMANENT with Gator-Clip-Jumper-Wire-B -> STILL: NO (!!!) Relay (and such) pulls / sticks. With the Gator-Clips (permanent) connected: You do tests on the playfield / in the cabinet / in the backbox. At the very moment a Relay (Score-Reel / Unit) CONSTANTLY (FAULTY) pulls / sticks: You pull the main power cord - and we talk about / look for THIS problem / fault.
(Unplug the main power cord), clip-on Jumper-Wire-A on / at Transformer-Lug-YELLOW (solid / secure clipped-on), then move Jumper-Wire-A around relays / units (no hindering of movement) through the open coin Door into the open and insulate the Gator-Clip (paperbag).
Then clip-on Jumper-Wire-B on / at "right flipper-switch-Lug-RED" -> move the wire into the open and insulate (paperbag).
Plug-in the main Power-Cord, start a game -> idle. NOW You put together "for a half of a second" the gator-clips "Wire-A" and "Wire-B", then open the connection.
"Important question***" - In the Backbox / in the Cabinet / underneath-side of the playfield: Is a relay / unit / Score-Reel pulling / sticking ? If the answer is "Yes": We MUST find the cause and fix that.
In a pin "fully running": we can make the "written above" -> the pin does not show a reaction. "Only / not until" us imitating "Ball rolls here and there".
Post-17, result of Test1: Fine, the bumper fires "as long as You make "Jumpering / connection" - it stops firing when you open the connection.
Result of Test2: I must adjust "Description-Alpha" a bit. At the very end of the "Start-Procedure" a "couple of things" may happen (depending on the model / pin). Your pin does not run 100 % - when You do connect Clip-on-Jumper-Wire-A and Clip-...B: These "couple of things" happen (late) now. I adjust "Description-Alpha" to: In a 100 % running pin the "couple of things" happen in the Start-Procedure - in Your "faulty running" pin these "couple of things" may happen "just after You made connection "A" and "B"".
So I also adjust my "Important question***" - ... You connect wire-A and wire-B -> a relay may pull / a stepper may step - BUT - shortly afterwards: Relay STOPS Pulling / "Coil on Stepper-Unit" QUITS Pulling. You keep-on connecting wire-A and wire-B -> NOTHING is pulling / sticking.
If (if) SOMETHING IS pulling / sticking: Report.
Some "Theory of pin-logic" / then "having a closer look at results of tests in post-17" ...
"Schema is drawn in a well defined state" - Think of the lifetime of a game: You plug-in the Main Power-Cord -> You start a game -> the pin does resetting (Score-Reels, Relay-Bank etc.) -> Balls fell into the trunk -> You lift the first ball up onto the Shooter-Lane (NO launching of the ball) -> You UNPLUG the Main Power-Cord (relays loose electricity and quit pulling): THIS is what the schema shows. (So the Tilt-Relay is resetted (no tilt), the Game-Over-Relay is set into "state ready for playing", all relays in the Reset-Bank are resetted.)
"Schema is an abstract drawing" - it does NOT show "reality in pin, the wiring" - it is drawn beautyful: Wires move in rectangular ways, (Power) Wire-Black goes straight from left to right, short wires (Black) branch-off and go to Lug-Black-on-Coil-of-Relay(s) - in the pin, reality : a wire-black comes (from Transformer-Power-Side) to Lug-Black and a wire-Black goes further to the next coil etc. The schema is an abstract. True is: I see a wire from "A" to "B" in the schema - in the pin: "A" and "B" ARE connected - maybe "A" is in the backbox and "B" is in the cabinet, the Jones-Plug (in the connection "backbox <-> cabinet") is NOT drawn in the schema.
"Result of test2 (post-17)": Do they "fire and let go" <-> "they fire constantly" ? "Fire constantly would be a severe fault" , "fire and let go" is to me "a minor fault , a fault but not harmful".
Please write about "fire and let go" <-> "fire constantly (pulling)".
Lets look in the schema: At F-11 I see the "Coil M29-1100 on the Red-Advance-Relay". look down a bit: a knot. From this knot I see wires going to the left / to the right / downwards. I follow (looking at one line / looking at the next line / and so on): I CANNOT get down to the loooong-wire-Yellow. Always a "Switch drawn open" hinders connection (down to YELLOW).
As a "working-hypotheses" I say: (Maybe) one of the switches "drawn at D-10" is "FAULTY-CLOSED" and allows / makes "FAULTY CONNECTION". Candidates are (D-10): "Left Bottom Roll Over Switch (playfield)", "Top Roll Over Switch (playfield)", "Red bumper SWITCH (to look for, later).
So check the top of the playfield: http://www.ipdb.org/showpic.pl?id=938&picno=64603&zoom=1 I assume: On the underneath-side of the playfield, at position "Yellow and Red advance" are TWO switches -> is one of them "FAULTY-CLOSED" ?
So check the Left Bottom playfield (underneath the playfield), http://www.ipdb.org/showpic.pl?id=938&picno=64601 : "Red Advance" -> Switch FAULTY-CLOSED" ?
So check the "Red Bumper Switch" - I do not know the pin - I BELIEVE (maybe I am wrong): here http://www.ipdb.org/showpic.pl?id=938&picno=64601 -> way up on the right, the "Passive Red Bumper", look underneath -> Switch FAULTY-CLOSED ?
I might be right with my "working-hypothesis" <-> I might be wrong - You find out about, please write.
"After results test2 (post 17) ... Things that work": I hope things do NOT "start-pulling-and-then-stick" - I hope: You can establish "PERMANENT CONNECTION jumpering transformer-Lug-YELLOW <-> Right-Flipper-Switch-Lug-RED" - You then can activate (by hand) things on the playfield -> relay(s) pull AND LET GO. Please write about "Things that work ..." (((Do not get upset - I MUST ask to fully understand Your writing))).
Greetings Rolf
