Hi Tom
some different problems - FIRST: Wrong forum, the "Tech and therefore Tech-Generic" is for Solidstate (electronic) pins. If my hints (here) do not help - may write one-more-post (?): Wrong forum, topic closed. THEN write a new topic in here: https://pinside.com/pinball/forum/forum/tech-em
SECOND: I am not good in Gottlieb TWO-Player-Games. Due to restrictions: ipdb.org is not allowed to show "paper stuff" - so the question is: Do You have the schematics / do You have the manual (write about). I show here "best I have - Big Brave".
THIRD: It is IMPORTANT that You write about "desoldering wires because had to do some cleaning - have soldered back on" or You (hopefully write) "have NOT unsoldered wires".
FOURTH: Is the problem ONLY with the HUNDRED Points --- means: You do NOT have the fault when strictly only "play and ONLY make a lot of 'ten points' " ? What happens when You make 70, 80, 90, 100, 110, 120 points ? Does the fault show up ?
I have never seen a Gottlieb-TWO-Player-Backbox / Player-Unit - here https://www.flippers.com/gott-sub-assemblies.html they ALSO have the FOUR-Player-Unit - the third picture, upmost wheel is black - it is wheel-5, below is wheel-4, -3, -2, -1 (all white). The switches in the switchstacks have letters, A, B, C ... --- the "A" is closest to the wheel / axis.
In my JPG we see in the upper right corner: "Switch-P2B" - (remember the "A" is closest to the wheel) - the wheel-2, a three-bladed Make-and-Brake-Switch does change between the two players.
WELL, important question - When fault shows up: What is seen in the Backglass: "First player playing" or "Second Player playing" ? Did the Player-Unit in the Backbox STEP ? (changing from player-1 to player-2 ?)
Do some tests - probably have to start an new (EM-Tech) topic - make a good desciption, greetings Rolf
