Few problems with my gottlieb Freddy pinball.

Drop targets will not reset in test mode or in game. I replaced solenoid and coil sleeve, re-heated up solder points on fuse holder for drop targets, replaced fuse and still nothing.

Shooter lane kicker works in test mode but during game when ball goes into lane I have to manually use plunger to hit ball. Not sure why it works in test mode but not in game. This is used for the ball save feature correct?

I just ordered manual from pinball resource. Where was the loose wire? I checked all connectors I couldn't find anything. I also noticed the claw flipper does not work either. I'm thinking maybe a bad diode. But I do have schimatic for switch matrix and says drop targets have their own diode. Would it be rare that all three diodes for drop targets are bad?
