Oh damn, That's why my new motor took a crap so quick! I replaced it and thought I did something wrong. $110 wasted. Gears were stripped. I took it apart and found the gear boxes to be cheap crap. My T-rex eats balls and that's good enough for me. If I still have it next year I'll update the ROM and get a new motor and try it again. Right now I'm still a little disgusted with it.

You just might get lucky I'm pretty sure the up/down switches have some room for adjustment and you may not have to disassemble the mech. It's a fussy setup but it is pretty cool. Good luck!

Hopefully that's it. Are those switches under the playfield or inside the rex? It's pretty tough to work on that part of the playfield underside as it's right at the bottom of the cabinet when fully raised.

Yeah they're easy to get to: two white ones on mine. Removing the mech is a pain:

Yeah good point because that part is really comfortable to work on although it's still dificult to get the whole mechanism out. I've done it a few times and don't look forward to doing it again. Also, you can go into diagnostics and use the fliiper buttons to eject balls out of the trough before tilting it all the way back.

Yep

Your first few issues could actually be just your settings (if your feelin' lucky)

Check game adjustment #33 Coils Pulse - make sure it's set to Normal. I turn mine down in the summer because I get low voltage at my house and the game resets when I get a lot coils firing.

Great!

Well, you're all ready for #2!
