Folks, My Bally Night Rider em is not lighting the extra ball outlane when all targets are dropped like it should. How this works is that when all 10 drop targets are down it actuates the Total Sequence relay which lights the target bank specials and extra ball outlanes. In my case the Total Sequence relay actuates lighting the specials but not the extra ball. I have cleaned the switches in the Total Sequence relay and am pretty sure this is a dirty or misadjusted score motor switch. My Bally schematic skills in locating score motor switches is poor. They dont list the score motor switch functions like Williams does. So I am hoping someone can help me locate the score motor switch that actuates the extra ball lights. The schematics are up on ipdb and I will attempt to paste them to this post. https://www.ipdb.org/files/1677/Bally_Night_Rider_Schematic.pdf
Thanks,

The SCORE MOTOR swtich only functions as a lock-in for the EXTRA BALL
relay. It's switch 6D which is the 6th cam from the motor end and the
4th switch from the bottom. Switch A is closest to the cam.
If you can manually actuate the EXTRA BALL relay and it stays locked in
then then 6D is not the problem.
My suspect is the make-break switch on the 00-90 unit. Make sure that
unit is stepping every time a 10 point score is made.
