I am new to owning and repairing pinball, but the lock ramp on my getaway machine seems to test fine in test mode. While playing though, when lock is lit the ramp lowers, ticks 3 times and then pops up, then repeats the same while lock is engaged. When the lock is not lit the ramp seems to sit a little low where the ball just drags the bottom of the ramp and can temporarly get stuck while in play until the ramp stops while the machine tries to find it. I don't know if these two problems are related but thought bringing up both might help. Any help would be appreciated. Thanks.
