I have a issue where my alien poker will add a credit when ball ejects from to shooter lane.
This only seems to happen around 1 in 5 times.

I have tried to trigger this manually by recycling the the first ball in play and draining it with no points to try and get it to add a credit but it wont do it.
Only seems to do it on that initial first eject.
both switches are not on same matrix and i have checked diodes and credit button needs to be pressed to actuate ....tried banging and vibration and that wont trigger it.
I also have Rottendog combo board installed

Any ideas

Forgot to add i have done switch tests and all shows fine with no phantoms

Good to hear I'm not the only one
Hopefully someone can chime in that has fixed this.

This is like Bill Cosby issue
Pretty soon we will have 20 people claiming the same thing and no results

Figured i would give this a sunday bump

Another bump ...i know there's a few with this issue but has anyone solved it yet?

It would be more fitting if this issue residing in a TZ machine

Hmm thanks for the info going to give that a try my diode tests good but I'll replace anyways
I'll let you all know results later

Ok I changed the diode and fixed one minor area on the ground braid i repaired. So i started some games and then I got excited on my 19th game start and still no 2nd player until my 20th try and got 2 players ...so i tried again and got it on my 16 try so it looks like what i did worked some.... sure is better than every other game. When i get some more time im going to look at some more ground connections and see if i can rid of this problem.
