Quoted from roddog:

Hello friends,
This is a x-post from the Metallica owner's thread (no reply to my question):
I am having issues with the SNAKE EJECT switch. I ran the switch test and threw a ball in the snakes jaw and the SNAKE EJECT did not show.
I fiddled under the playfield and concluded that it is not an issue with the button not being suppressed. I was able to press the button and the switch would still not show up on the switch test.
So I opened the manual and can see the switch on the SWITCH MATRIX GRID. Not sure what it tells me though. No idea how these things work. It says it is switch #54, and something about a GRN-YEL and WHT-BLU wire...
Not sure how to troubleshoot this or what to do from here. Any help or tips or references would be greatly appreciated!
Thanks!
