im sure you know this, but a dmd for that is going to run 450!
if either of you want to verify its parts.....send them to me!
i dont bite.....and im an honest guy!
ill check your stuff free, just cover shipping!
ill tell you if your dmd is toast or not....mine works 100%, so if your isnt fried ill get something......and i dont trust that guy either, when you receive the mpu back send it my way and ill test on my machine
sorry you had to go through this, im went through a similiar experiance with my fish tales(still a work in progress)

Sorry to hear about the fried DMD. I can guarantee it was dead when he sold it to you. He does this all the time, he will take a picture of a "working game" then swap parts. Then when you either receive it or go see it in person he'll rush you around so that you cannot inspect it properly.
Leave negative feedback on Ebay if you can. If you need me to go to his place to get parts I can do that also.

I got the CPU and dmd back. Had a few minutes so I installed the CPU. The bootup lights were correct, which is farther then it ever got before. I then hooked up all the other plugs to it and it keeps resetting I believe. It does the train whistle then some drums or gunshots, hard to tell, then resets. It stops resetting if I undo the ground plug for the CPU, so it must be a stuck coil or something. I had previously unhooked about 5 coils that I believe were locked, but I'm going to hook them back up and start diagnosing from the beginning, now that the CPU works correctly. I don't know if I can without a working dmd but I'll see.. I can buy another dmd, but I really need to verify the pinouts for the plugs for it. As I've stated before, there is no plug going to the P2 terminal of the dmd. It's the one where 12 and 5 volts come into the dmd. I think I got the voltages from the online repair manual, but Im not sure which pin is pin 1.
Is it ok to unplug all plugs from the CPU, then plug in it's power, then plug in all the others, one at a time, to try and figure out which one is causing it to start resetting?
Man, I talk a lot!

Ok. Figured out the resetting was bad connection. Game is now up!!!! It smoked one coil, so I unhooked that one, but plays. Paddlewheel boat and all drops work, as do most lights.
Looks to need the up kicker coil, two thumpers rebuilt, a few bulbs, and of course, a new dmd. not too bad though, considering how this project started.
I think I'll get the dmd so that I can use it's diagnostics for the game, but overall, I'm feeling better about it now.
I've had it on for hours and we have played many games, guess I'll throw another 500 bucks at it for the dmd!!!! Yeah

great news, DD.....glad you got it to play blind. very cool.
throw a new DMD in there and you should be rockin'......remember, you gotta post some vids once you get it up and running 100%.....not many maverick vids out there.

Congrats DD!
When you get some time on the flippers let us know what your impression of gameplay is...
Im looking at a bulk buy and there is a Maverick in there.
Thanks and GOOD WORK!

Hopefully this helps!
as you can see in the pic, j2 connects with p1, that would explain why you got nothing!
take a look!

worked in the garage all day and had Maverick on a long time. we played multiple games with no issues at all. it's amazing when you try not to hit a target, I.e. The up kicker, which doesn't work, how often you actually hit it! I ordered a new dmd from Bay Area, and threw in the Cruisn Usa button you boys wouldn't scan for me!!!
I'll let you guys know hopefully soon that's it's all up and fully functioning.
also, somebody with a Maverick could maybe verify the dmd plugs for me. I have a plug to go in the J7, but I would like to verify it's wire voltages, in case they have been reversed. also the DMD P2, which had no plug going to it, need to know if somethings supposed to be there. it's not the data cable... Online manual seems to indicate 5and 12 volts go to it, but again, I have no plug available that would possible go there.
Thanks

THIS IS MY MAVERICK DMD, this is how YOURS SHOULD LOOK, if its not.....well make it that way!.........if your missing cable you could go to a computer supply store with it and either they can make the cable for you or they can tell you how to make it yourself
and pin one is usually red on the cable unlike all the others, on the board it should have a 1,
not really sure what help your wanting if you dont listen

I have been listening and appreciate your picture, but that doesn't show what I am asking about, which is, again, the P2 plug on the DMD itself. It's under the controller board. Your picture doesn't seem to show anything plugged in there but the online repair manual indicates that there should be. P2. P2. your picture shows the J7 I believe. I have that plug, I'm just trying to figure out about the P2
OP
OP
The power wires for the DMD......not the data wires. I would like to verify the voltages for J7 and for P2, if something plugs into it, P2.
Don't know if this helps, but I have a Batman Forever. Same DMD AFAIK, and it seems to look like dc2010's. In dc2010's picture, the vertical ribbon cable on the left side goes from P2 on the DMD PCB to J2 on the controller board.
OP
OP
Thanks again for verifying that, but I really could care less about the ribbon cable. I have never in this whole post asked about that, but that seems to be the only answers I get.
Again, on the DMD itself, mine has a 4 wire plugged into J7. J7! I would like the correct voltages for those wires.
and also again, my DMD has a connection labeled P2. That's P2! There was nothing plugged in there. Should there be something there, and if so, what are the pinout voltages? The online repair manual says there should be, but DCs picture doesn't show anything there.
I don't mean to be abrupt, but I have asked this same thing throughout this thread and have never gotten an answer. DC seems to think I was asking about the data cable? Or something? I stand confused.
The power wire in DCs picture is going to a terminal labeled J7. I get that, I have that plugged in there.. That's all good. The P2 terminal on the dmd is all I'm asking about
I guess I give up on asking

We must have different PCBs for our DMD boards. I don't have a J7 anywhere. You are asking about P2 on the DMD board, correct? That is what I answered. I have something plugged in there: the ribbon cable that goes to J2 on the controller board. That's why we keep bringing up the ribbon cable, it is plugged into P2 on our DMDs. Sorry if this isn't what you want, but it is all the info I have. And I think it is why you keep getting these answers that are frustrating you. My DMD board only has P2 and P3, that's it.
In looking at my BF manual, there are schematics for three different display boards: Cherry, Babcock, and Dale. However I don't see a J7 on any of the schematics for any of the boards, either the DMD or the controller.
So maybe you have a different DMD that is just plain wrong for Maverick? Or we have different DMD PCBs from yours? Or who knows??? If I get the time and energy tomorrow I can remove my controller board and take a picture of the DMD PCB itself. No guarantees.

Your probably right.. This is confusing! Mine has the Cherry display but I ordered a new one and I don't know what brand it is. The Maverick manual shows J7, but I can't really read the voltages or whatever it says. The P2 I'm taking about is on the DMD itself. In an earlier post I posted a pic of it.
All pictures I find don't seem to show anything plugged in there, so maybe the online repair manual is wrong?
That big plug with blue black and red wires in DCs picture is labeled J7 on mine. Hopefully DC can confirm that
