Which switch ? Was the trough switch wired correctly etc ?
Glad to hear it works 
There were a couple of things.
Switch 08 which I will call the ball eject switch wasn't registering when the ball was sitting on it. When Adam pushed the ball a bit it was enough for the switch to register and he could start a game. I adjusted the switch arm as well as cleaning the leaf contacts which were pretty dirty and that solved that problem.
Switch 28 which is the switch that was being concentrated on throughout the thread wasn't wired correctly. We had a look at the pics of other Xenon owner's switches and couldn't confirm that they were the exact same switch so we couldn't guarantee that just copying the way someone else's machine was wired up was necessarily going to work for this machine. After a bit of trial and error, we found a configuration that worked...the ball ejected when it was supposed to with only one ball at a time being loaded into the shooter lane as opposed to having both balls eject. This all in turn got the tube kickout working properly as well seeing as it was on the same column in the switch matrix.
Adam may be able to upload a pic of the way we ended up wiring switch 28 ????
