Hello everybody

I am a happy new owner of a JP Premium and still pretty new to the hobby.
I bought the game of a guy who had 50 plays on it and didn't got to play much and so didn't even find some of the problems out of the box.
One problem was an oversensitiv pop bumper, that was a pretty easy fix adjusting the switch.

The more funny problem is, that the switches for the control room aka c-shot and the raptor pit seem to be wired incorectly. In the switch-test, the control room is the raptor pit and the raptor pit is the control room.

The switch has two cables, green and black. I am not realy sure what to do. My feeling tells me, to switch those cables but a new guy and still learning a lot about electronics.

Thanks a lot for your help!

That is a picture of the switch under the control room (left) and the raptor pit (right). Green, black or both cables?
Thanks a lot.

Thanks for your help. I will check it in the evening ( I live in Switzerland) and write back asap. I have this picture, but I don't think it's helping. Front switch should be control room.

Thanks for everybodys help so far.

So I had a closer look and took the following pictures. To me, both cables are lgn. There are no grey stripes. They both go into Nodeboard 9, CN11 next to each other.

Well... it is kind of a mess. The lgn-grey cable goes to the raptor pid -up left switch and gets regognised so in the switch test. Raptor Pit - Top and Control Room are both lgn cables.

Ok... I think I found one of the problems... I am definitly colorblind. I wasn't able to see the grey stripe. Sorry everybody.
It looks like the lgn gry is in input pin 3 and the lgn is in input pin 2. On the Switches the colours are correct. lgn gry on Control Room and lgn on Raptor Pit - top.
Can I just pull them out and stick them in or do I need to watch for something?

Thanks to everybody for the help.
The fix was in the end easy but I learned a lot on the way . Just had to change the cables on the molex connector. Screwdriver did the job very well.

I noticed that my trex somtimes loses the ball, altough I have set the adjustment to:

"T-REX THROW BALL ENABLED" - NO

Did someone had to deal with similar issues?

Yes. While moving the head right to left, she opens her mouth and looses the ball.

All FACTORY settings on the T-Rex, just the "T-REX THROW BALL ENABLED" - has been changed to NO.

Two out of three times she does it right. Maybe I will contact my distributer for this one. Watch and learn.

Which mode is it? Trex multiball it works most of the time and trex chase it allways worked so far.

You have been able to deal with the mouth sticking open by cutting a slice of the upper jaw didn't you?
Could it also be a problem with the coil?

I already tried to cut a bit of the upper jaw, but it did not help so far. I am hesitant on how much more I should cut of.

Thank you for your tip.
Some days ago it worked perfectly three times in a row. But now the Trex never went through the chomping motion in about twenty tries in a row.

My only problem is the trex mutliball. All other trex modes work fine, because she chews the ball only during trex multiball. In the coil test she opens her mouth with the jaw opening test and closes the mouth with the magnet test.
I am not sure what the opto switch test is.
And also, where is the close jaw test? Or is it the magnet test?

I will try that. Thanks

Is it possible, that during the coil test the Trex should close her mouth while activating the Trex mouth magnet? Because mine does not.

Now after 2 houres of playing the game, it suddenly started working properly. Maybe it really has something to do with the temperature. But the temperature of what exactly?

Also do you know, what mecanisme closes the Trex jaw?

Thanks so much

Heyho

I am definatly not the first guy with this problem but I have can not find a awnser right now.

So when I hit the right ramp, the wireform should guide the ball perfectly to the right flipper. On my maschine the ball often bounces left and right after exiting the wireform and then I am not able to hit it with the upper flipper. I think the wireform exit is to much in the center and should be farther on the right, in a way that the wire on the right (from the three wires of the wireform) is perfectly above the ball guide.

What and where should I bend? I am not sure what to do.

Thanks for your help!

Thanks for your response.
I forgot to mention what I allready did, my fault. I did not only play with the attachment points, I went further and took appart the whole ramp. Nothing helped so far. The only short fix was to press the wire on the right behind the ball guide. It stuck there for a game and then... o wonder it worked perfectly. But it does not last there long by just stucking it behind the ball guide.
