About to join the club.
Picking up tomorrow morning.
Have wanted this game for over 10 years. Not easy to come by!

From the pics the seller shared of the game it looks to be in great condition. Mentioned that the right slot spins slower than the others. I believe Planetary has new wheels/motors for this.

Anything in particular to look for in person (aside from accessive elevator ramp fractures an whatnot)?

Thanks for the tips! I’ll look at all these sections when I pick it up in 2 hours!

Hi everyone

Just finished shopping a Who Dunnit i recently picked up and while I've diagnosed and fixed a ton of issues I am still having a problem with the left slot motor.

Long story short, I purchased a new motor from Marco and can't get the thing to work! All the PCB boards work correctly (tested each with the other two reel motors and the baords are all fine).
Starting to think the "plug and play" motor from Marco may be misswired for the PCB connections.

Has anyone else purchased one of these marco motors and if yours works can you look at the wiring to see if it's the same as mine in the pics below?
Mine is wired top to bottom: Red/Green/Yellow/Blue.
The other two motors (originals i believe) in my game are wired: Red/Yellow/Brown/Orange

Thanks fellow WD detectives!

I compared the best I could and the wiring seems correct. These wires go directly from the stepper to the PCB board. I actually took apart the old stepper motor and tried cleaning it up. It manually functions a bit better now. May try putting the old motor in again and testing it to see what happens. Won’t take the whole reel assembly apart... will just plug the old stepper into the PCB and cross my fingers.

Apologies.
I should have mentioned that I tried swapping the new stepper motor with one of the other PCB boards that is currently running a working slot reel.
The new motor still didn't spin which is what lead me to think it is the new stepper motor wiring.
I actually bought 2 new motors to have a backup.
Will try both of them as well as the old motor again on one of the working boards.

I'll also test the transistors in the non-working stepper motor PCB board just in case.
Such a crazy mech that shouldn't be this complicated. Hahaha.
Thanks again for your thoughts/feedback, Mancave!
Fingers crossed.

Tested everything again.
I think I figured it out.
It's TOTALLY the new motors from Marco.
I tried the new motors (both of them this time) in all the functioning PCB boards. Nothing.
Then I cleaned out the old motor a bit so the gears were less jammed and tried it in all the PCB boards. It worked in each of them.
So it has to be the wiring in the new motors from Marco.
Gonna email them for their thoughts since their site said it was "plug and play" for Who Dunnit.

In the meantime, if there are any Who Dunnit owners with new Marco Stepper motors in their games can you please let me know the order in which your wires are inserted into the molex.
Thanks everyone!

UPDATE

Fixed the motor issue!
Ryan over at Marco's customer service figured it out!
Long story short, the insertion crimp the motors came with wasn't making a firm connection/bite with the IDC connector.
So I crimped new contacts to the wires and used a molex connector.
The reels are spinning perfectly now.

Are your reels all spinning in the correct direction (towards the flippers)? One of my reels was spinning the opposite direction when I got it so I had to re-wire the molex connector.

I would check your motor wiring on the connectors that go into the motor boards.

I recently shopped my Who Dunnit and took a boatload of pics. Will go look at them and get back you you if I notice where they may go.

Wow.
Went through all the pics and can’t find where those spacers should go.
Noticed on mine the only spacers are for the spotlights, left ramp exit over the slingshot plastic, and the right ramp just behind the sewer.
It’s possible there is supposed to be a spacer on the right slingshot plastic to push the magnifying glass plastic up a bit to crate a “3D” effect.
Possible that those spacers may go under the top playfield plastics somewhere but didn’t notice where they could go in my shop out pics.
The mystery continues...

I would push Butler off a building for a new elevator ramp

Clever idea to remake the elevator scoop! Mine is cracked but not too bad and I was able to use some plastic solvent to fix the crack and make it super strong. The “elevator ramp” usually refers to the 3 exit ramp on top of the elevator scoop. Apparently that ramp mold is unobtainium
and the process to make it is very cumbersome. Sucks because almost everyone with a W?D could use a new elevator ramp.

Damn! Trixie is a babe on your game!

Have you taken the motor out/apart and cleaned it? Could be that there are metal shavings causing issues.
Another thing I’ve read is that the optos may not be reading the reel’s decal spaces appropriately.

Just two top of mind things to look at.
I had issues with my 3rd reel and the culprit was the motor. I installed a new one and it fixed the issues (once I got the correct molex re-wiring schematic from Marco).

I found the post(s) that speak about the opto/reel issue.
Give a read and see if this relates to your scenario.

One of my wheels scrapes the opto a bit as well because it is a bit warped. Thankfully there are replacements.

I used something similar to fill in the cracks on my elevator ramp. I suggest removing the ramp to be safe since it’s easy to get drips. That’s what I did and was worth the hassle.

The end result was great. Very strong stuff that really does weld the plastic together.

But I hope the ramp guys remake this ramp someday!

Which color DMD do you have installed?
LED or LCD?
It looks awesome and I want to add one to mine in the near future.

Sounds like one of the switches on the left and right orbit/taxi lanes isnt registering and telling the ramp to lift up.

There’s the up post that diverts the ball to the pops. Is that working properly?

So if all the switches are working in the left/right taxi orbits then my only other thought is that the up/down ramp mech is being flaky. Have you checked the little micro switch in that actual mech? I believe it’s a little roller switch inside the mech if I’m remembering correctly. I pulled mine and rebuilt it a while ago but will look for pics.

I’m mistaken. It’s a normal cherry switch.

Check out my post in this thread.
Post 343 I believe.
I purchased new motors from Marco that were Miss wired but once in the right order all my motors started spinning correctly.

I double checked an email chain I had with Marco’s tech who helped my solve my wiring problem with their new motors.
For the new motor, the wiring should be:
RED pin 1
GREEN pin 2
YELLOW pin 5
BLUE pin 6

Same ware spots are on my W?D.
I added a little clear nail polish on mine and put a strip of Mylar over it.

Looks like Xmas came early this year!
These look great. So glad they are finally able to be reproduced!

I’ve checked their website everyday for the past week and haven’t seen it yet. Maybe the first lot were presold or reserved.

Installed mine as well. Fit perfectly.
Makes my W?D look (and play) so much better!

Ironically one of my wheels spins similarly when I test it outside of the machine like you did. There is a tiny bit of grind somewhere like yours. Spins fluidly during gameplay so I just left it as is.

Correct. Checked mine and can confirm yours is mounted upside-down.
