Hi pinballman3
Dr_of Style said it: "Look at the EOS-Switch". OK, Look in the manual "Cabaret": http://mirror2.ipdb.org/files/415/Williams_1968_Cabaret_Instruction_Manual_no_schematics.pdf -> page-15. Almost every Score-Reel has this End-Of-Stroke-Switch - see it standing upright ? The plunger - at end of its travel will OPEN this switch -> the XXX-Point-RELAY looses connection and lets go.
So we suspect a faulty-bent blade on this EOS-Switch "Player-1-Score-Reel-10'000s-Points" - NOT OPENING ...
And if the fault also is on Player-2, -3, -4: ALSO look at the 10'000s Score-Reels of player-2, -3, -4.

Hi pinballman3
do You have a schema ? do You have a manual ? Please write about.

The ball on the playfield hits a target worth 10'000 points -> the target closes a switch -> current can flow -> the 10'000 point RELAY gets active -> it closes switches -> one switch closing should let current flow to the 10'000s-Score-Reel of WHICH player - THE PLAYER UNIT KNOWS WHICH PLAYER I PLAYING - through contacts on the Player-Unit the current is send to the approbiate Score-Reel. If a wire has broken-off somewhere in this way: The Coil on the score-drum does NOT fire - also: the coil can be shot / not working.

Look here: http://www.ipdb.org/showpic.pl?id=2449&picno=55536 -> lower left corner: the Player-Unit. Look at my JPG - it is from the Manual of "Sonic: Faces": http://www.ipdb.org/machine.cgi?id=806 -> instruction-manual-page-19. This Unit is shown "player-1 is playing". If the pin moves to 2nd player: The round bakelite plate will be stepped one step counterclockwise. I have drawn some "violet lines" - a connection.

Player-1 is playing -> ball hits a target -> 10'000 relay pulls -> through my "RED-Line" current flows to Player-1-10'000-Drum-Unit-Coil.

For safety reason: UNPLUG the 110 VAC Main-Cord.
Please look at the Player Unit: Are the wires soldered-on ? the encircled 19, 20, 21, 22, 23 ? well actually: all wires should be soldered-on. Grab each wire and gently pull a bit -> REALLY soldered-on ?

The fault can be in many places - we start our search for the fault AT THE PLAYER UNIT. Please check the Player-Unit and report - maybe we are lucky - maybe we must look other places.

For testing Coils on Units / relay-coils:
Do You (already) have some Jumper-Wires witch Gator-Clips on the ends ?
A Test-Lite is also handy - in another "Topic" / "other problems" Steve Fury shows a wonderful "Test-Light for testing 24 Volt (Relays) Circuitry ((24 VOLT !!!),
Here: https://pinside.com/pinball/forum/topic/reading-gottlieb-schematics post-12. In post-10 he writes about testing (I also made myself this handy tool).

Hi pinballman3
do You have a schema ? do You have a manual ? If You do not find the missing piece: We should have the schema - and the manual would be very helpful. We can guess "Player-Unit of Super Straight" is identical to "Player Unit Faces" - we could use the schema "Faces" - a big problem are "Wire-Colors""Super Straight <-> Faces".

Sonic pins are "clones" of Williams - the used Williams Parts. You could try to get a spare "Player Unit of a fairly modern Williams pin" - or maybe just the missing piece (asking in pinside).

For documentation -> here: http://www.planetarypinball.com/reference/partsmanuals/WMS_Parts_1977-1978/index.html#/8/zoomed and http://www.planetarypinball.com/reference/partsmanuals/WMS_Parts_1977-1978/index.html#/11/zoomed - no help.

A new topic with a picture "pieces of the Player Unit I have - can you help me getting a replacement part" - do You see on ...-page-8 / -11 the missing part -> maybe asking PBR ? (telling them the Part-Number)

If You cannot get the part: Mounting the two bakelite plates on a "spare Williams Unit" - a lot of work - but with schema and manual You can get the alignment.

No spare part AND no spare Wms-Unit: You can make your pin to be an "ONLY-SINGLE-Player-Game" You fix the two bakelite-plates and the Snowshoe-wipers in between tohether IN POSITION "First Player" - You always ONLY start a One-player-game.

Think of: Williams and Ballys have "Ball-Count-Unit BCU" and Player-Unit P-U". Lets say the pin is set for "3 balls per play".
The sequence of a 1-player-game is "P-U=1, BCU=1" -> "P-U=1, BCU=2" -> "P-U=1, BCU=3" -> Game-Over.

The Player-Unit ONLY steps forward in a multiplayer-game - example a two-player-game:
"P-U=1, BCU=1" -> "P-U=2, BCU=1" -> "P-U=1, BCU=2" -> "P-U=2, BCU=2" ... -> Game-Over.
So either a spare part or a spare unit or a "single-player-game".

In Switzerland / Germany its now 11:30 at night (23:30) - I go to sleep - I wonder what I read from You. Greetings Rolf

Hi pinballman3
fine - no lost part. The title of this topic is "Bell-Coil" - is the problem "scoring 10'000 Points" solved ? If so: Please mark the topic as "solved" (and give a short explanation: The fault was ...). THEN start a new topic "Sonic Super Straight is always a 4-player-game" (((short description of the problem You actually have))). Think of: In the future somebody has a problem -> he does search the pinside-forums -> He'd like to read about THAT specific problem.

Yes, the Coin-Unit is resetted at start of a new game (Position-Zero means only ONE player wants to play the next game). The Coin-Unit will be stepped-up to "2" / "3" / "4" players want to play.

If the Coin-Unit does not work properly - if the Player-Unit does not work properly - if these two units have "problems in communication": We have problems as "always a four-player game" and such problems. Schema-Faces-area-D-6 shows the communication in between these two units.

Start a new topic and write a good description of what happens when You want to play a 1-player-game / ... 2-player-game / ...3 / ...4. Greetings Rolf
