Having some drop target issues.
#1: operates and works exceptionally, no problems ever.
#2: will operate fine in the drop target test mode once or twice, and then will immediately stop firing for the knockdown, no noise or anything from the solenoid, the reset still activates. This causes balls to get stuck after a game is completed with a locked ball still there, and in turn cause a never ending pinball search because the game wont drop the second target. If I leave it in drop target test mode long enough, it will randomly register a #2 knockdown, it could be every five cycles, every 10, sometimes won't do it for upwards of 20 cycles and then will randomly just drop fine once and then continue the lack of response indefinitely. I assume this must be an electrical issue? Switch responds perfectly fine it test mode, and all optos are aligned and responding perfectly.
#3: Won't drop, definitely mechanical as the game will still fire the solenoid for both the knockdown and the reset, but target will not drop. Drops perfectly fine if you manually hit it with a ball, but the solenoid will not knock it down no matter how long in test mode. With game off i can press down on the metal plate that the mini solenoid pulls in to activate the brass arm everrrr so slightly and it will drop the target, but when the solenoid is activating and seemingly hitting the target with more force, it does not drop. Tried bumping up the solenoid power to no avail.
Would very much appreciate any info on either of these issues, i have tried readjusting both microswitches by adjusting the screws that hold it to the frame and troubleshooting it at every possible angle/tightness/looseness and it makes no difference.
Thanks!!!
