TECH: LOTR Tower Diverter Gate

[Paul]

My tower diverter gate has a nervous condition all of a sudden. There is
no switch? Just a coil. In test works fine, but during gameplay and you
get War of the Ents when the gate is held open during the timed play, it
vibrates and sometimes has a hard time holding it open. I know its not
the coil. What should I be looking for next?

Not sure if you have already ruled this out, but I believe the tower ge
shuts when Orthanc being fed from the right loop (possibly the left loo
as well, not at all sure about that one).

If one of these switches was intermittent, it could cause a problem?

I am not sure if it would cause twitching or not, but it could explai
why you are not seeing this problem in test (test would not care abou
other playfield switches).

Just an idea...

Good timing, I just ran into this same issue after I completed a shop
job last night. If it's what I had, it can be fixed by a simple
adjustment to where in the plunger stroke the gate is tightened. I'd
originally set it so that the "open" position of the gate matched the
"open" position of the plunger. The gate has such a small range of
motion that when the coil was activated, the plunger would only come
halfway into it, causing the gate to twitch while the plunger hung in
the middle and the coil kept trying to tug it in more. I adjusted it
so that the "closed" position of the gate corresponds to the
"closed" (against the coil stop) position of the plunger and all seems
well.

Oh, the same procedure can minimize buzz from the leaning tower as well.

I should clarify my post and say that when I said "open", I meant gate
to the left. Long story short, the guide Cody posted is the same as
what I did to fix it. (Hey, good to know I did it right. Thanks for
adding that.)
