Hi yzfguy
we players may believe "stepping down the Bonus-Ladder makes on every step the 1000-Point-Score-Drum to step". Not true, true is: Two features happen at the same time - stepping down the Bonus-Ladder - pulsing the 1000-Point-Relay to give points.
See the JPG, single Bonus - switch B on Impulse Cam fires 5 times per turn of 180 degrees (Score-Motor) - the Bonus-Unit is stepped down. At the same time another switch, switch-C (also on Impulse Cam) fires 5 times per turn of 180 degrees (Score-Motor) - the 1000-Point-Relay is made to pull-in - and again and again ...
See the JPG, double bonus - limitation in time (scoring points) makes it necessary to slow down on the stepping --- see the bottom of the JPG - Brown question marks: The area where the fault is. Greetings Rolf
