Thanks!

Thanks, I saw that too. But really only need this 1 plastic, must be sold separatly somewhere?

Need help on how to move T-Rex to the center position manually?
It cant be moved in the menu due to malfunctiobing motor i think, I need to have it centered. Tried to push it by hand but it didnt move, I didnt want to push too hard.

What screws should I loosen? Is it done from under the playfield or above?

Thanks!

Thanks! Do u mean the up/down motor or the left/right? A pic would help, if u have any many thanks!

@Bucknaked, thanks man, really appreciate your help

Got 12 coils that wont work, neither in test menu nor in play. According to seller, they worked before shipment. Tested the fuses and they seem fine. What to do next?

Coils are #:
7R,
11-21,
1R

(Note: the switches registers fine, for instance the pop bumber and slingshot switches are ok, but coils dont fire)
Any ideas are appreciated, thanks

That´s my thought as well, but where is the common power? Trying to figure it out from the manual, but I feel lost

Thanks, I'll mesure those!
Where in the manual can I found a coil matrix or similar, to know what coils are sharing the same wiring, and where in the backbox they should go(what transistor) so that I can check continuty?

I only find a switch matrix but not for coils :/

So, an update to my issue regarding the 12 coils that are not working:

- There is no voltage when measuring at the coils

- Power Supply CN3:
Pin 5 is 85VDC (not sure what it should be)
Pin 6,7,8 should be 34VDC, I get 1,1VDC (!!)
Pin 10 should have continuty to pin 3 and ground, but it don't

- PPB, J6:
Pin 1,2,3 should be 32VDC, I get 84VDC
Pin 6,7 should be 28VDC, I get 84VDC. Also, there should be continuty to F7 but I can´t seem to find F7?

- PPB, J7: All values are OK (should be 50VDC, I get 74VDC)

Really appreciate if someone can guide me from here. Fuses are OK (exept for F7 which I can´t find). I think my problem is with CN3 pin 6,7,8 - what could be causing this low value? Are the values for J6/J7 on the PPB OK, or why are they so high?

This is my first Data East, I´m only used to Williams.
Should I post this on the general forum instead?

Cheers

Anyone know a guide, pics or anything where I can find info on how to adjust the switches on T-Rex?
Seems that I need to take out the whole thing to be able to get to the screws that holds som of the switches?

Any info would be great, thanks!

Oh and I read somethibg about a set screw, what's that?

Thanks, I already have seen this and yes, it is really helpful
However, I was looking for instructions on how to disamble, or what to disamble (in what order etc), to get to the swithes so I can adjust them.

Also, a really stupid question, but adjusting switches is simply a matter of unscrewing the switches and re-srewing them onto the same place (same screw holes) but with a slithly different position then before?
Tried that on one of the switches but couldnt get it to trigger, the only way is to bend the switch which I know is a big no-no.

How do u guys do it?

Yes! Unplugging the whole trex sounds like a great idea!
Are there any instructions for that? Like is it only done under the playfield or is something supposed to be removed from above as well?

Thanks a lot man, got the t-rex out now!

I have been going through looots of pics in this forum trying to find close-ups of the switches, especially the up and down switches.

If anyone plz can take a photo of the up and down switches (while mounted on T-rex), it would be nice

Thanks!

OK, sitting and trying to adjust the Trex switches now. Would appreciate a quick answer: The up/down motor should only spin one direction, right? This means that it goes all the way around (circle movement) between the up and down switches, not forth and back between them?
So every time one of the switches is triggered, the motor has spun 360 degrees (well not the motor itself, but the "pin" that triggers the switch). Or am I wrong?

Can anyone verify my statement PLZ?
Thanks

Thank u all, t-rex is eating the balls now
However, i managed to create myself a new problem while removing the under-playfield ramp to get T-rex out. The ramp broke where it connects at the right VUK.

Plz if anyone could take a picture of that spot, I need to figure how the VUK switch should be in relation to the ramp (under the playfield)

Thanks!

I am still struggeling with the right VUK switch. The arm (actuator) on the switch snapped off, so I am trying to make my own arm.

I cant get the arm to trigger when the ball sits in the cup, but it triggers with my finger.

PLEASE, I really need a pic! It would really help if someone could take a pic of that arm! I want to see if I am doing right where it touches the ball cup.
PLEASE

Here is my (non-working) solution:

I know that part but couldnt find it in Sweden, so I am trying to do my own arm to look like the one in the picture.
However, it is hard to tell how it looks like at the end, where it "connects" to the ball cup.
I need to see a pic mounted on the game.

Thanks

jesperpark thanks, the 2nd pic was pretty helpful. Still though I need to see how the arm touches the underside of the ball cup, couldnt tell from the pictures since there is no ball cup in the 2nd pic.

Thanks a lot for trying mate

An update regarding the right VUK switch arm:
After HOURS (!!) of trying to make an arm for the switch, I noticed that the switch do register now, while in diagnostic mode, BUT it says that it is switch nr9 "Through #1 Left", while it should register nr61 "right VUK"!! So it seems that the wrong switch registers when the ball hits the VUK switch, no wonder why the VUK dont fire then.

It seems that the wires going to the switch have the right colors.

Where to go from here?

Oh, thanks that sound good to check!
Well should I check all diods on all switches, or can I narrow it down to only test the ones within the same column/row?

Hi, great forum this!
Previous issue is solved, it was the diode

Now a new issue: dino picks up ball but it stays in his mouth. He tries to swallow 3 times but often without success.

I read other posts about this. One post mention the up-switch, but this is checked and OK, there is no slack further back when pushing my finger on dino while he is in up position.
I dont think it is the playfield incline (angle) either.

The only thing I found that I havent tried yet is this:
"There's supposed to be a black rubber pad behind the t-rex where the plunger arm from the coil presses into when the t-rex stands up."

So I wonder if anyone can describe where I find this black rubber? I dont understand the desciption.

Many thanks!

Anyone that has scanned playfield plastics and can share the files?

I found some old posts but with outdated links.

I want to try to make my own plastics, so hit me if you have any scanned plastic - especially the slingshot plastics.

Thanks
