New to the club. Just got a Shadow in with some issues.

The first one :

Mini playfield is not working. Testing : Optos on the playfield are ok, optos beneath the playfield left /right from coil are ok.
All cables seems to be ok, reseated the 3 plugs.
LED 1 is on
Coil gives 11ohm...?? is this ok? I thought a coil only should give 5ohm ?
when I do the motor test left or right nothing moves...

How to test the motor and the coil?

other ideas ?

That's the one with the LED on I guess, the LED is on, what else and how to check?

It's not sliding from left to right sliding when I push it, you can feel small resistance from the motor but it moves freely and you can feel the gear turning. Think this is ok.

There is only one under the mini playfield + 2 optos on little PCB's and 2 strips holding the lamps.
Is the one you speak off under the main playfield?

There is indeed a small board but I think it controls the optos. the red black/wire goes to opto on playfield. The grey/black I think to optos under playfield. The motor has a red and white/yellowish cable.
When power is on, LED onboard is on as well and both optos seems to work according to switch edge test.

OK will do..

The LED on this little PCB is off when Pin is on, is that normal ?

There is no power on pin 1 and 4 on J2 (tested with motor on selection in test menu and motor off, should be 20V I think)
I reseated connector J116 and J126 on the PDB (they look ok and all cables are tight)
I also noticed LED 3 on the PDB is off, but no idea if there is a link, just mentioning...

When starting a game without balls the kicker moves while in search of balls at game start... meaning it gets power...

Strange issue with opto /switch 47 inner loop.
Test reports it's open (It should be closed i suppose)
Replaced both optos Rx/Tx with new ones.
Problem still there : Open in test mode, and no reaction when i put something in between.
On the connector just before the opto I measure 12V on Grey/Yell - Black cable. (going to Tx)
On the opto i measure 1.2V on the TX and nothing on Rx. (OK?)

Manuel says cable should be Green/Yellow (switch 47) and goes to J207-4 via J3-3 op the main opto board
There is however no Green/yellow cable connected on the optos but an Orange/Brown going to J2-8 (connected to the receiving opto)

Tried my cell in camera mode in front of the Tx : nothing.
Can't imagine a new one is broken...
Anything i can check or measure on the optoboard or elsewhere?

Thx

All other optos on that board are working, can a LM339 just fail for one switch?
And indeed the orange/violet cable is going directly from the opto receiver to the opto board at plug J2 -1. (Switch matrix cable is another story)

How can I check the output at the board?

Forgive my ignorance but how to compare? what pin with what pin and what should it give as result to be functioning ok?
Unfortunetly not on a socket

Found the schematics and it seems to be controlled by LM339 on U2B (Pin 4 - and pin 5+) Next question is what should it measure in value ? to be ok in close and open mode ?

Just swapped the LM339 for a new one (on socket this time). No changes !!!
It's indeed pin 1 on J2 for switch 47 (receiver side).
I can't break the beam, it's already broken as reported as open in switch test... and can't close it..

Tested violet resistors. All have 268ohms. Al diodes are fine as well (+/- 590).

The U2 located LM339 controls 3 optos (45-46-47)
45 / 46 are closed (ok) and report 4.3V
47 (faulty remains open) reports 11.6V
Pin 3 (Vcc+) and pin 12 GND report 11.6V as well

What can I conclude with these figures?

Found the issue ! 12V reached the small connector 2" away from the opto but didn't pass to the receiver. I was told earlier 1.2V on sender was ok and 0V on receiver also, that's why initially i didn't investigate further. But now I know it must be 12V on the receiver !

Other and hope final issue... to finally be able to play hassle free.

The left diverter is no longer reacting on the left blue button. If I do a solenoid test it moves in both directions.
So it gets power and instructions but not via the button. Cables are ok on button side.
What and where can i measure values ?

Phurba left control is switch 34 and test says it's open.
Hitting the left blue button has no effect.
No reaction in edge test

Continuity on both cables is ok (from soldering on switch to connector on MPU) Diode on switch gives 509 in diode mode.
Only strange thing is they are connected on J206-3 & J208-4 while they should be on J207-3 & j209-4 and normally 206 and 208 have no connector (Manual says not used).
These connectors are bridged so that's fine but on 207 & 209 there is also a cable connected... ??
It worked till I solved my opto problem yesterday... strange...

I switched connectors from 206 to 207 and 208 to 209. Don't ask me why but everything works now...
TIME TO PLAY !!!

Did any of you removed the standard speaker panel and went all black without it?
Considering to give it a try with these decals on the speakers.
The standard blue one is awful with my translite...

Degustibus et coloribus non disputandum est.

The translite is not the point....

Does anyone know if the speaker panel of a Who Dunnit would fit the shadow ? It's black with golden Bally logo.

Yeah with the roundings not very nice. Problem is the blue panel doesn’t fit with my translite (see previous post) was going to add the phurba stickers.

Have red/Blue LED's on my transparant flipper buttons (already installed when bought)

These are 12V but left side isn't working anymore. The used boards are no longer sold, so I'll have to switch to 6.3V wedge with 2cm flexible wire LED's.

What's the best point to pickup 6.3V/GND near the left flipper buttons ?

Thx good info !

LEDs on flipper buttons up and runing, left GI 6.3V and right 12V with LED PCB's.

Also installed color PIN2DMD !! Very good investment !

Does anyone know which font is used in eg : Punish the guilty.
It seems no one is selling insert decals so might do kind of own production....

Super thx !!
