Just got a Gottlieb Stargate in the shop for a shop job. There were many issues with switches and broken mechs.
All have been resolved but one still lingers.
Anytime the machine is on (Getting Power) Both of the right flippers can be activated with the right flipper button as if the machine was in gameplay.
I tried disconnecting both sensor boards and even out of the circuit the flippers can still be activated.
I am not familiar with system 3 this is my first in the shop.
I also installed a new right side flipper button switch assembly with new caps as the old was really shot.
I have never seen this issue on amy machine before any ideas?
