These lights are driving me crazy. I have adjusted both sets of optos on the Warp ramp. I just did the ones at the top of the ramp and before I slid the glass back on I tried hitting the ramp with the flipper. It lit up ten out of ten shots. Then I put the glass back on and started a game. First four shots up the ramp, no lights.

I have lower my optos to be flush with the holes in the plastic and all issues are gone

Mine often do not work and I'm not convinced it is the result of the optos. I can manually trip the optos, get the sound effects and DMD animation, but still not have the chase lights activate.

If the right loop switch is tripped without any other switches being hit (ie soft plunge for the super skill shot), every time I have tested it, they do not work. Tripping another switch usually reactivates them. It seems like there is something in the code.

Sounds like at least partially software to me.

I'm convinced it is software as well.

Do you mean centred with the hole? I have lowered mine and it does not seem to help. Or do you mean you moved them in towards the plastic ramp?

I've had issues even making the shot more than once in a game!
I've heard that you can adjust the ramp somehow. Anyone know how?? Did you see improvement??

As for the lights, I've only seen them work on occasion.

yes you can adjust the ramp with a screw that is in a slotted hole at the end of the ramp near the corner of the playfield mine would return balls to the shooter lane lol. adjusted the ramp and now can make shots much easier.

I lowered the optos to be center with the hole that is cut and as close to the hole as possible.
