Hi padarjohn +
a great site --- here http://www.zaccaria-pinball.com/em/index.html on the left click on "Games and Documentation" and there are many schematics. The schematics "Universe" is in 5 pages nicely overlapping but not page-4 and page-5. See the top of the JPG (here) - please confirm "I can draw as connecting lines 'my red lines' " --- or write / show a JPG (taken with an mobile phone camera): "Some stuff is missing at end of page-4 / beginning of page-5 respectively".

You must fix Your "second issue" --- a general rule is "a coil on a relay or unit is allowed to faulty, constantly pull for 1 to 2 minutes - we then must toggle-off and let the coil cool down - otherwise the coil overheats, get destroyed --- and we must buy an new coil".
See the bottom of the JPG - when a plunger is moved on a Score-Drum (on most): The travelling plunger at end of travel opens a switch to cut feeding electricity to the "Coil on 100-Point-RELAY". Greetings Rolf

Hi padarjohn
I agree with You on "the drawing of the schematics in not very good" --- but I am glad this site exists: http://www.zaccaria-pinball.com/em/index.html .

See the JPG here --- upper part: I will put a gap in my copy and add ??? and add "stuff missing ?" in the gap. (((I think that nothing is missing - but there is a little chance of "missing")))

In post-4 You mentioned "two unlabeled switches" - see the JPG here, lower part: I added "Gottlieb text" --- You kind of agreed and wrote "will check the E.O.S.-Switch on the Score-Reel". Greetings Rolf

Hi padarjohn
to "Bonus Unit faulty resetting" --- You do have some more EM-Pins. Ask a friend to press the Replay-Button and You look how the Replay-Counter steps down a step --- actually two halfsteps --- one tooth pulled back frees the gear BUT another tooth mooves-in to hinder "rushing all the way down". Then look in the "Universe Pin" for sticky grease etc.

The schematics gives me some headaches - before I dig-in into the Drop-Target-Points problem some questions --- here https://www.ipdb.org/showpic.pl?id=2706&picno=37539&zoom=1 on the bottom of the picture I see "Outlanes give 5000 points, Inlanes give 500 points" and on top of the picture I see "100 500 1000 5000 10'000 points when lit" ---
do You always get (reliable) the 500 points, 5000 points ?

From where do You have the information "Drop-Target is worth 5000 points ?

Some units under the playfield --- can we see them in one of the ipdb-pictures ? --- In the "Lights section of the schematics" I see drawn three units --- can You go by "color of wires" and match schematics and "units under the playfield" ? Greetings Rolf

Hi padarjohn
great findings - Your post-8. The stepper-units (post-9) --- wear rubber gloves (electricity can kill people) - manually step a unit, then look on the playfield - what light(s) have turned on / off / stepped ? or check color of wires (in the pin vs. schematics). Power-issue (?) in post-10 --- can You live with it for a while ? No, I do not think about 50 vs. 60 Hertz. In the schematics follow the line/wire where power comes out of the transformer - to fuse - switch on Reset-Relay - switch on Game-Over-Relay - switch on Tilt-Relay --- a long wiring in the schematics ending on flipper-coils. There can be a bad solderpoint somewhere or maybe one of the mentioned switches is no good.

I do some theory "making 5000 points" but first some words about the Score-Motor. The Score-Motor is a willing helper but has no intelligence. All a motor can do is: Start running when Initial-Current comes to the motor, turning and actuating ALL switchstacks / switches as designed when the motor was built. When Initial-Current endlessly comes to the motor the motor runs endlessly. The Initial-Current is made to stop flowing at a time but the motor has (early in the turning) built-up its own Self-Feeding circuitry so the motor runs further a bit, then stops on the next Home-Position.

See the JPG - the played ball leaves the playfield through an Outlane worth 5000 points - switch (my green-1) closes - this makes the 5000-Point-Relay (green-2) to pull-in. Several switches do actuate as the relay pulls-in - "green-3a" I call "Self-Hold-Switch on the 5000-Point-Relay" closing and the relay stays pulling, "green-3b" closes, I call it feature switch***. "green-3c" closes and makes the motor to run (Initial-Current flows to the motor (green-4). The motor starts turning, shortly after the motor closes "blue-5a" - this is the Self-Hold-Switch on the motor - the motor keeps running. The turning motor closes five times "blue-5b" - AND through the closed "green-3b" !!! the 1000-Point-Relay actuate five times (((and in an subfeature makes the Score-Drum step, five times). The motor turns, opens "blue-5c" means CUT the Self-Hold-Circuitry of "green-2" (the relay let go and opens its "green-3a, green-3b, green-3c" --- the 5000-Point-Relay no longer pulls. The opening of "green-3c" cuts Initial-Current-Circuitry on the motor - but the motor keeps-on running (through its Self-Hold-Switch "blue-5a") --- turns further, reaches Home-Position so "closed blue-5a" opens - the motor stops.

I must say: There are some faults drawn in the schematics --- for sure faulty is "End-Of-Stroke-Switch on the flippers" (see bottom of the JPG).
About in the middle of the JPG I made a red point, a connection on wires --- (((otherwise I could / can not make the 5000-Point-Relay to pull-in ...

feature switch***: The Motor HAS NO intelligence - ALWAYS ALL switches actuate when the motor does a turn (of 180 degrees) - ONLY when the feature switch*** is closed: THEN the closing of the motor-switch five times (my blue-5b) is allowed to reach the 1000-Point-Relay. When the pin is helping another caller for help: NO 1000ds of points are wanted, guaranteed by "not closed 'my blue-5b' ". Greetings Rolf

Hi - sorry, I made a fault in writing - PLEASE read the beginning of post-15.

Hi padarjohn
great - You fix problems (post-14). Grumble, I was carefully writing my post-13 and at the very end I made an typo-error - correct is: ... When the pin is helping another caller for help: NO 1000ds of points are wanted, guaranteed by "not closed 'my green-3b, the feature-switch on the feature relay' ".

Lets think of "the manufacturer did not want to give 5000 points when the ball drains through an Outlane --- the manufacturer only want to give 3000 points". How to be done, implemented ? One solution is - see the bottom of the JPG: We see on the Impulse-Cams when three times switches are actuated - when the third times closing electricity was sent --- instead of cam-5, switch "my blue 5c" to open and so cut Self-Hold-Ciruitry on 5000-point-relay: A switch on cam-4 (maybe cam-3 ?) does open and so cut --- the last two pulses through closing "my blue 5b" cannot pass as the feature-relay no longer pulls, the feature-switch no longer is closed.

Something I love on Williams pins (many do have it) - Your pin also has: See the JPG on the right, somewhat down, orange and green: The Self-Hold-Switch on the Score-Motor (for the Score-Motor to keep running) is OUTMOST Switch on CAM-INDEX. Whenever we chase faults and need a turn of 180 degrees of the Score-Motor: We gently press down*** and let go the outmost blade on Index-Cam - the motor makes a turn. Of course: NO feature relay pulls, no feature-switch is closed - nothing really is happening but the turn of 180 degrees of the motor. We chase faults, use Jumper-Wires, we manipulate stuff - we easily can make the motor to run for to help our testing. I really do love "outmost-switch on cam-INDEX is the Self-Hold-Switch for the Score-Motor.

press down***: For safety reasons please wear rubber gloves (for insulation) - or maybe a rubbered index finger. Greetings Rolf
