Hello everyone,
I finally got everything working on my pin buuuut there still is the "player 3 issue".
Though player 1,2 and 4 count their points how they should, player three "randomly" (or rather saying about each third time) counts 100 points, although only a 10 point target is hit. I already checked the contacts of the scoring wheels and they look fine. I tried to simulate the error to see which relay switches (faulty) but until now I couldn't find anything suspicious.

Hence I couldn't find anything using the search function - does anyone have a clue which parts I should pay attention to?
Or - in case this is a typical/ 1000times discussed fault tell me which keywords I must use to find the corresponding thread?

Many thanks for your help

Hi Fred,
sorry for my bad description. It actually is the first scenario - 100 points are "randomly" counted on player's 3 scoring reel. "Randomly", because there seems to be a correlation between the position of the 00-90 unit and the 100 scoring reel of player 3.

I'm gonna check all switches once I'm back home - thanks a lot for your procedure.

That actually was much easier than I thought. Thanks to your description I got a better understanding how to read the schematic. In the end it was the end of stroke switch of player 3, 10 point reel, which was adjusted to closely. Finally I got my pin fully working. Thank you so much !!!
