sensitive drop targets

[pinball god]

tried the search button but what a waste of time.   I have a single bank drop target that will tend to drop due to the pop bumpers and lots of shaking of the machine. Could someone please explain if there is a way of adjusting the position the target sits on the playfield ledge or something?

I could make the spring less tight but if there is a better way I'd like to hear it. thank you

Sounds like the entire assembly is located too close to the edge of the playfield hole for the DT.

On reset, the target should move "up" and "forward" so the tab on the target sits on the lip of the metal housing. If the assembly is too far forward, then the target tab won't be sitting on the metal housing properly.

As Nino suggested Rob.  I don't know the type of drop bank assemblies on your S.I, but make sure its sitting square.  I have seen where OPs have bent the whole assembly by hand (just a smidge) towards or away from the playfield for this adjustment....Although I don't think its one that would be printed in the manual...

thanks guys, I took the ledge plate off, struggled to put it back but seems to seat better on it now. Stuffed if I know what I did. There does not seem to be any elongated holes so that you have the opportunity to move it slightly away or towards the target  Maybe that's why the ops use the bending method???

No elongated holes in the assembly brackets. But sometimes smaller screws (in diameter), and these allow movement.

Could also simply be that a previous owner may have lubricated the area, which is always a bad idea as over the years all the crap gets attracted and the moving parts become sloppy - this causes all sorts of issues.
