Does someone have a written "Theory of Operation" for a Vari-Target system in a Gottlieb EM (particularly College Queens). Right now, after starting a game, both Vari-Target reset coils lock on (the ones on the assemblies themselves). The Vari Target reset relay is not enabled.
As a result, the vari targets do not register anything. If I manually trip the Vari-Target Reset Relay on the motor board, the target coils release. I can then score points with either one, and when the reset relay releases the individual coils on the target assemblies lock back on and will not work.
I am really not exactly sure what is supposed to happen in sequence (should any of the coils be locked on all the time, etc.). OR...something like a startup sequence:
1) Ball 1 ejected in shooter lane and all coils related to Vari Target are off.
2) Ball strikes Vari Target, energizing the Right VariTarget score relay
3) Vari Target score relay, through score motor switch 2A, enables VariTarget reset relay
Thanks in advance -
