Goodmorning everyone. I have an Italian copy of TEN UP Gottlieb pinball machine TEX OP. It is for one player only (add a ball). Unfortunately it doesn't have a schematic but the relays and connections are very, very similar to the TEN UP. In fact the relays that give me the problems are exactly in sequence like those of the TEN UP.
While you are playing, sometimes, when the holes at the top (hole relay) are activated the motor makes one revolution, sometimes continues with the loop (ta ta ta ta ta) or makes one more revolution sometimes 3 sometimes 5 and most of the time nothing.
This loop with the "ta ta ta ta ta" does it in these other three cases:
1) when the ball return relay is activated
2) when the wow relay is activated
3) when the sequence completed control relay is activated
Cleaned and adjusted all engine contacts but without definitive results or improved but not resolved.
Are there any other contacts affected besides the motor and its relays?
I attach the link of the video so as to give a better idea.
(sorry for the google translation ....)
