I had a very strange thing happening on my shadow. I noticed when I would hit the drop target to enter the mini playfield with a solid shot it would trigger the switch and light the right ramp left divert ring. Specifically with a hard shot that would fling the ball up hitting the wire form. The switch (77) on the wireform is above the drop target in the fling path so to speak. Very annoying and I figured I had an issue with my switch matrix. I went through all the tests and tried to get both switches to register in switch test. All functioned properly after 50 or so attempts to see if a bad diode etc was triggering the other switch (77). They are not on the same column or row so I figured it was a mechanical issue. I even replaced the ramp switch entirely. I then pinched the switch blade so it was not loose in case the hits were causing the blade to bounce triggering the switch. This issue didn't happen all the time, only when I had a really strong solid hit in which the drop target would fling the ball up hitting the wire form near the switch on the ramp. I tried to replicate triggering the switch by manually hitting the wireform with the ball, etc. I could not get it to trigger this way. The only way the switch (77) would trigger was if I really tossed it good, again, causing the ball to fling up and bounce off the wire form. I make airball mods for drop targets for Indiana Jones and Tales from the Crypt. I quickly made a prototype and it seemed to remedy the problem. No phantom ramp triggers. If I made officials they would be cut much better and not extend out over the shadow loop. You can barely see it when installed because the battlefield covers it.
Is it my machine or are others having this problem? It is very hard to noticed because it is a fast game and one may just think they made the ramp shot. I could make these (they would look much better) if it is a problem. I don't remember having the issue on my other shadows but maybe I wasn't paying attention. I noticed it because I am absolutely neurotic about my games playing perfectly.
It's a pain in the ass to test. I put my game in switch edges, partially raised playfield and I toss the ball at the drop. Then I manually lift the drop by reaching under the playfield. You can also play without the glass and keep taking shots at the drop target and after it drops send it back up the vux into the battlefield to reset the drop. Try again.
Let me know if your game is acting this way or it is just me.
