I recently bought STTNG, and the right flipper flips upper flipper first, then bottom flipper. I'm expecting it to be the other way around so that I can hold a ball and still shoot delta quadrant during multiball; am I right about that or is the upper flipper intended to flip first?

thanks

Not sure, but it seems wrong to me, too.

Switch test mode can tell you if the correct flipper button switches are being triggered.

Flipper test mode can tell you if the flippers are wired correctly.

Correct, something's not right, they should hit at the same time.

Quoted from NoTellin:

they should hit at the same time.

Uh... I was thinking lower flipper should be first stage, upper flipper should be second stage. I know that's how Addams Family and White Water work, which were made around the same time...

The bottom should always fire first and the problem is probably dirty flipper optos or/and a bad opto interrupter. In switch edge test when you push the right flipper button slowly you should see the bottom opto close then the upper one.

Thanks for all the responses - sorry I didn't check back ... at first it seemed like my thread was stillborn and then I forgot about it.

On STTNG it is easy enough to swap the wires for SW1 and SW2 on each flipper opto assembly, and that fixed it. It's obvious, too, that it was backwards because the wrong way round wasn't flipping the flippers in single switch test, while with the wires as expected, the flippers flip, same as they do on my Addams, and you can check that the EOS's are lighting up.

I was wondering the exact same thing a few days ago... it seemed odd to me that the upper flipper would fire first, but after doing some research, I could confirm this was factory default. I swapped the two switch wires on the idc connector - simple fix, more precise game play.
