Hi Alan_L +
the "1 card point score reel for the first player buzzes" ONLY when You are playing. I am not familiar with the logic of play, Here is what I see in the ipdb-schematics.
Starting a game makes the "1" close as the Coin-Relay pulls-in. This makes the "2" pull-in and it establish " (3) Self-Hold-Circuitry for a long time" - until all is resetted (4 stuff) - then the "2" drops out. When playing the reset is done everytime a new ball is given (5,6,3,4). The motor is running so "7" pulses - through "8, 9 closed by pulling relay", "10" is the "11" stepped.
Now my problems of understanding the logic: Through running motor, pulsing "7" and pulling relay "either 12 or 13 closed" - then "14": The "11" is also stepped five (?) times. Please write about the No.-1- and No.-2-Relays.
When playing the pulling Target-Relay closes "15" and through "14" the coil "11" fires.
I would look at and clean the switches "12,13,14,15" - do You see sparks ?
(((Funny - I was looking for snippets of schematics to my Gtb Ice Revue and stumbled over))) Here https://pinside.com/pinball/forum/topic/game-over-light they also talk about resistors. I am not an electricien so I do not know - interesting is (the whole topic and) post-8, POST-12, post-15 and on.
The No. Match Unit sticking sometimes: HowardR (post-6) shows the schematics and asks about the "Switch on the 1-Point-Relay" - is this switch adjusted tight - sometimes faulty closed when the relay is not pulling ? We also see on the snippet "when the Player-Reset-Relay is pulling and the motor runs:" A stepping is done - therefore it may be that these "Switches involved" are adjusted tight (?).
Alan_L --- in post-5 You write "NONE of the 1-Point-Switches work" --- maybe they do work - make the 1-Point-RELAY pull-in and then this RELAY keeps-on faulty pulling - so the No-Match-Unit is just a symptom of the faulty endlessly pulling 1-Point-Relay (?). Greetings Rolf
