Quoted from Geeterman1:How do I pop the target up while in switch test mode? I popped it up in the coil settings and then manually popped it down with my finger while in switch test and nothing registered. I did the same with the center drop targets and they all registered so the switch isn’t registering when the drop target is going down?
Any idea what type of switch this is and how to fix?
OK, you'll have to take the balls out and raise the playfield up so you can access the underside of that area.
You can see the bottom of that drop target when the playfield is in the full upright position and leaning against the backbox.
That target has a plastic flange that passes between a U-shaped opto switch in (I think) the down position.
I had the problem in my UM where it would not register when the flange was supposed to be breaking the infrared opto beam because the translucent plastic was allowing the beam to pass through instead of blocking it. I had to paint the flange black. That may be your issue, or something else may be not working with that opto switch.
