I was helping my father with his T2 pin lastnight but couldn't figure out what was causing the issue. The drpp target under the Terminator head won't stay up. When you shoot the ball into the area behind the target it is then supposed to shoot back up while the ball goes over to the "gun". The target will pop up but then drops back down. It does this 5 times in a row then just stays down.

I figure it has to be 1 of 2 things. Either the sensor that says that the target was hit (so it will drop) is mis-aligned so it keeps dropping or whatever is supposed to catch the target to keep it up is not catching. I spent about 30 minutes checking it out lastnight but there is so much going on back there that it was damn near impossible to tell what is what on the back of the playfield. I found the solenoid that pops the target back up and the switch that senses when it is down but I couldn't find the switch that senses when it is hit.

Any ideas?
 
Anyone have an idea why the drop target won't stay up when it pops back up? I spent awhile searching on the Pinball Resource site but didn't find anything noteworthy... did learn a lot of other stuff though. HELP :)
 
Did you check to see if the blade microswitch is functioning properly? Page 2-23 of the manual looks like the assembly that your talking about?? Maybe a wire came off, or it's worn out..

Will check this tomorrow (Saturday) and report back... thanks. If the pin were at my house I would have probably fixed it by now but with it at his house I can't dedicate the time to it I would like. Not that my father is inept... I think he's just wary of trying to do to much with it because he doesn't want to screw up something he spent so much money on...... so it comes down to me. :)
 
Alright. I finally got some time at my parents house to work with the game. So it seems the microswitch is working fine. Basically, when the target is down and a ball is shot behind it under the skull the drop target is supposed to pop back up. It does pop up but doesn't catch so it drops right back down and retries popping up 6 more times before it gives up and just stays down. I found that if you're looking at page 2-23 in the manual the notch on the back of the target (item 1) is not catching with the Single Stop Target (item 14). If you manually push the target back up and press up on it you can get the target4 notch to catch with the SST (item 14) but it feels as though the target just isn't popping up high enough to catch on it's own. And it's really only a matter of being less than a milimeter too low. It's not that the coil isn't popping it up high enough because it is lifting it the full range of it's motion (the plate at the bottom of the "reset assembly" (item 8) is lifting as high as it can). It's like the target slipped down in its assembly a tiny bit but enough that it won't catch. Is there any way to adjust this? Maybe by loosening the nut at the bottom of item 8? I still haven't got a great idea of all that I can do/move in this assembly which is why I'm looking for direction. If I were at home I'd scan the page in the manual with the diagram and circle the parts I'm refering to.

Any ideas?
 
I know I need to see images so here is what he is referring to...

Fantastic, thank you. I will reply with a few notes on the diagram in MS Paint after I make sure my son isn't going to splash too much water out of the bathtub.
 
Basically, "A" is the target. When it resets (lifts back up), "B" is supposed to catch on "C" to keep the target up. But "B" (the tab on the back of the target) doesn't get high enough anymore to catch with "C" (the tab on the assembly). If I push on the target ("A") with it lifted I can get "B" to catch on "C" but otherwise they are less than a millimeter from catching.

any ideas? I'm stumped as to what might need adjusting to get the two pieces to catch.
 
Is it definitely not getting high enough or could it be that it isn't pushing forward to hold once it gets up there? Just thinking around the issue to make sure it's not something obvious. I would think one of those springs pulls it forward a bit.

Yeah, it has to be something obvious because I'm certain all the switches check out just fine. The spring that pushes the target forward is fine. From what I can tell it is just literally not getting the target up high enough for the two parts to catch.
 
There is a arm that mounts to the bottom of the coil plunger (#8 Plate and reset Assy). And when the coil activates and pulls up, that arm grabs the drop target and pulls it up. That piece might be getting flimsy or maybe just needs bent up a little because that coil is only going to go up so far before it hits the coil stop.

That is what I was thinking too but I wasn't sure what I could and couldn't move in there. But I will get in there to see what I can do. May be that the target slipped down (I don't know how it's mounted right off hand). May be that I need to bend the plate up a little bit... I'll check it out and report back.

Thanks for the image too...

For the sake of documenting the outcome for archival sake, this was the issue. Tonight I took another look at the pin while we were at their house and it looked as though the arm that pushes the target back up had bent down a bit. So I grabbed ahold of it and bent it back up and now it latches in the up position with no problem. Thanks for all the help I got here. I'm definitely still learning my way around pins so I will be doing a lot of reading. Next up is figuring out why the MPU-2 board on my father's Sharpshooter isn't getting any power... ... ... at least I fixed one pin tonight. :)
