Hi pinsiders
when You have knowledge of Add-A-Ball-Pins: Please help.
Hi gameover1173
99% of the pins imported into Switzerland were Four-Player-Pins. AAB-Pins are ultra-rare. I have little knowledge on AAB-Pins.
Thanks for the pictures of schematics. See the JPG - in the JPG on top from "around number 14" leftbound is the Power-side-connection. Some switches (I have marked green) control a bunch / group of stuff --- please show this section on "Jungle King".
In the first JPG in Your post-4 we see "Switch on H-Relay with wire-color-orange and with wire-color-black-red soldered-on. The switch is closed when the H-Relay is not pulling. The Tilt-Light also has wire-of-color-orange --- on the other side of the Tilt-Light is wire of color-unknown to me.
Unplug the main power cord (Safety Reasons) - take a Jumper-Wire and clip-on at "Switch on H-Relay, side wire-orange is soldered-on. Then take the other end of the looooong Jumper-Wire to the Tilt-Light and clip-on at Solder-Lug "wire-orange". With this Jumper-Wire You guarantee connection on a existing but maybe faulty wiring in the pin. Do manually step the Ball-Count-Unit up - do manually step it down - can You manually step ? Then step the unit in a middle position.
Then plug-in, toggle-on - Does the Tilt-Light lights up ? Then start a game - does the Ball-Count-Unit move / step ? Greetings Rolf
