Quoted from Lambecka:
Sorry yes right misunderstanding, iwas in the understanding the search disk.
Search index yes can be moved forwards, but don,t understand the effect by doing this
there's two units that can stop the search wipers from spinning:
1] the search wiper lock magnet aka search index lock magnet
nice name ... it's the relay-looking thing directly under the wipers at the edge of the metal shelf that the R-button powers. It's only job is to lock the search wipers in a harmless place so they aren't spinning continuously like in the earlier games. Continuous spinning is noisy and wears down the contacts and search relays.
this unit is positioned to lock the wiper contacts with the red mark anywhere at position 2 +/- 1/2 (not position 1 as said on the gerlitz video - that won't work on screen games because position 1 rivets are connected to the game circuits). Typically the search wipers are locked between rivets at positions 2-3, and if present, the position of the switch stack above the wipers is adjusted to be sitting up on the peg poking out of the locking cam.
2] the search index unit
this guy stops the wipers on winning rivet locations for inline wins, and possibly winning rivets on section wins. As OKO said, the black metal search ratchet/gear is directly connected to the search wiper shaft. Stop the metal ratchet from spinning, you stop the wipers from spinning. When you slide the search index unit forward a little on the metal shelf, the wipers will stop earlier on the rivets (more counter-clockwise).
if you follow the suggested steps above, there's no guessing. It's easy to find the position needed for the search index unit.
just in case the term isn't known, the armature is the metal plate the coil pulls down....you stick your finger in next to the switches and push it down onto the coil top. If you spin the search wipers clockwise, the search index unit will slide backwards. Push the index unit forward to get the wipers contacts where you want and tighten down the index unit.
a symptom of a search index unit that is too far back is the search index coil powering and releasing immediately. If the search index is too far forward, the armature can hit the top of the previous ratchet tooth and cause the wipers to not stop correctly either.
Other things can cause the search index coil to lose power too fast, but they are less common and more work to find, so do the position check/adjust first.
