Quoted from wrd1972_PinDoc:Back from the dead.
When the second ball is locked. My TAF absolutely WONT kick the third ball into the shooter lane UNLESS the coin door is open.
Defintely has something to do with the white interlock switch that detects door open or closed. It just started doing this out of the blue. But it's repeatable every single time.
Leave the door open and the 3rd ball kicks out like it should everything. Freaking weird.
I am also seeing some intermittent issue with switch 53 bookcase opto1. Wonder if it's related.
All switches in the swamp and trough test out perfectly.
Did you find out the cause and fix?
